[Suggestion][EXP-Editor] Wider text fields for the currently selected tilesets

[IchoTolot]

I noticed that the text boxes that are used to select the currently active tilesets (main theme + terrain/object select) are very small and even to such a degree that some names can't be fully read. Also, I am not able to resize them to a degree in which everything is readable to manually fix the issue.

A bigger text box that displays all names fully would be appreciated. I would rather advice to make it too big than too small -- rather be sure to display everything than cutting off names and cause confusion.

I made the theme text box larger, but there simply isn't more space for the piece selection box to become bigger.
