* more info about export conflict
* Update Export.gd
* Update ExportDialog.tscn
* fixed a small mistake
Removed the tool option signals from Main.gd and put them to ColorAndToolOptions.gd. Instead of having 2 methods for left and right, they are now in one method, using a boolean to differentiate between left and right.
* Added selective frame tag export for Spritesheets
* Changes LinesCount value and max_value to canvas_size
This does not allow the spritesheet to contain more frames than the tag has, because it limits its size to the number of frames the currently selected tag has.
