Update 0.4.6

Additions

• Added improved descriptions to Affinities, Tomes and Cultures with icons.
• Banner shield and icons now look crisp.

Fixes

• Some banner icons looked rotated to better fit the Texture Atlas. They shouldn't be rotated now.
• Input Text fields now don't erase all previous text, and the selected text is much more visible. 

Known Bugs

• Screenshot images are generated as JPG and are a bit blurry. Will try to fix for the next patch.
