Fix client-side particle texture errors (#82)

Somewhere between minetest v5.8 and 5.9, it stopped allowing texture modifiers without a baseimg

ERROR[Main]: generateImage(): baseimg is NULL (attempted to create texture "")
ERROR[Main]: generateImagePart(): baseime == NUL for part_of_name="[colorize:#FB0:255", cancelling.

+
+Requiring 16 blocks of tin and constructed in a circular fashion, a finished frame is seven blocks wide, seven blocks high, and stands vertically like a doorway.@n@nThese travel a distance along the ground, and even when constructed deep underground will link back up to the surface. They appear to favor a strange direction, with the exit portal linking back only for as long as the portal stays open — attempting to reopen a portal from the exit doorway leads to a new destination along this favored direction. It has stymied our ability to study the behavior of these portals because without constructing dual portals and keeping both open it's hard to step through more than one and still be able to return home.@n@nDue to such difficulties, we never learned what determines the direction and distance where the matching twin portal will appear, and I have lost my friend and protégé. In cavalier youth and with little more than a rucksack, Coudreau has decided to follow the chain as far as it goes, and has not been seen since. Coudreau believes it works in epicycles, but I am not convinced. Still, I cling to the hope that one day the portal will open and Coudreau will step out from whichever place leads to this one, perhaps with an epic tale to tell.=Для создания портала требуется 16 блоков олова, выложенных по кругу; готовая рама достигает семи блоков в ширину и высоту, стоя вертикально, подобно двери.@n@nЭти порталы могут вести на большое расстояние, и даже если они построены глубоко под землёй, их выход зачастую находится на поверхности. Порталы, похоже, следуют странному направлению, где выход ведёт обратно только до тех пор, пока портал остаётся открытым. Если попытаться открыть портал заново из выходной точки, он приведёт в новое место по этому загадочному маршруту. Это осложняет наше изучение этих порталов, ведь без одновременного поддержания работы двух порталов трудно пройти через один из них и всё же вернуться обратно.@n@nИз-за таких трудностей мы так и не выяснили, что определяет направление и расстояние, на котором появится связанный портал. Я потерял друга и ученика. С юношеской бесшабашностью и с одним лишь рюкзаком на плечах, Кудро решил следовать по цепи порталов до самого конца и с тех пор не давал о себе знать. Кудро полагает, что порталы работают по принципу эпициклов, но я не убеждён. Тем не менее, я надеюсь, что однажды портал откроется и Кудро выйдет из него — оттуда, куда ведёт этот портал, — и, возможно, расскажет нам эпическую историю о своих странствиях.
+
+Requiring 21 blocks of ice, and constructed in the shape of a 3 × 3 platform with walls, or like a bowl. A finished platform is 2 blocks high, and 5 blocks wide at the widest in both directions.@n@nThis portal is different to the others, rather than acting akin to a doorway it appears to the eye more like a small pool of water which can be stepped into. Upon setting foot in the portal we found ourselves at a tremendous altitude.@1=Для создания этого портала требуется 21 блок льда, выложенных в форме платформы 3 × 3 с боковыми стенками, напоминающей чашу. Завершённая конструкция достигает высоты двух блоков и в самой широкой части составляет пять блоков в обе стороны.@n@nВ отличие от других порталов, этот скорее напоминает маленький водоём, в который можно шагнуть, чем обычную дверную арку. Когда мы ступили на поверхность портала, то внезапно оказались на невероятной высоте.@1
+
+Surface Portal=Поверхностный портал
+
+There is a floating land of hills and forests up there, over the edges of which is a perilous drop all the way back down to sea level. We have not found how far these pristine lands extend. I have half a mind to retire there one day.=Там, наверху, простирается парящий мир холмов и лесов, с опасными обрывами, за которыми — головокружительное падение обратно до самого уровня моря. Насколько далеко раскинулись эти нетронутые земли, мы пока не знаем. Порой я ловлю себя на мысли, что однажды стоило бы уйти туда навсегда.
