Version 0.3.0

Breaking changes:

• The radial menu now balances buttons if there is a different number on both sides. If you want to retrieve the old behavior, set radial_choice_button_y_balance to False in the menu's file.

Miscellaneous changes:

• Added demo for the new radial_choice_button_y_balance parameter.
• The demo will now show the screen inspector by default.
• Fixed punctuation typos in the documentation.
