Revert 1469424 and fix wrong char position when doing mouse selection on intlGUIEditBox (#5806) 

* Revert 1469424075 and fix wrong char position when doing mouse selection on intlGUIEditBox

position should look at current line not the whole text and shift 1 character on the last line (due to \0 string delimiter)

* Finish the fix and prevent values under zero for getCursorPos which crash the program if found

* Forget to remove old comment

* fix zero to NULL

* Fix typo
