Happy National Sticky Buns Day!

This version fixes key issues in the previous release.

• adds a missing keyboard key for Numpad Plus
• implements a sane and simpler version of setup reloading that actually works (it now 'remembers' your last setups and gamepad switching)
• implements a UI for Gamepad Testing (and keyboard/mouse testing)
• minor cosmetic fixes to various settings panels in ICUI
• fixes cosmetic and associative problems in ICUI's action drawing function
• changes the way InputCandy handles keyboard/mouse and player association (simpler and easier to change!)

The next version (0.9.5) will implement the final UI element of ICUI: input capture, an alternative way to set input configuration for the player that opens up the ability for players to create virtual thumbsticks and remap functionality between disparate input axis.
