Version 1.22 changelog

Fixed a rare circumstance where controller support would be disabled on the Steam version of the game, with no obvious way to turn it back on.
XInput (XBox 360) controllers can now be detected even if their DirectInput drivers are not currently functioning.
Added a new Setting that disables up+attack=spear throw, instead requiring a separate button be mapped for spear throw, to prevent accidental spear throws by players who prefer to use a separate button.
Added a new Setting that disables down+jump=dodge roll, instead requiring a separate button be mapped for dodge roll, to prevent accidental dodge rolls by players who prefer to use a separate button.
Up+Attack (Spear) and Down+Jump (Roll) shortcut buttons are now mapped to controller buttons in the default control scheme.
Camera no longer resets to close-up zoom when change maps while have the toggle zoom option set.
Using Alt+Return in Full Screen Windowed mode now goes to a normal window instead of immediately switching to Full Screen mode (which made it look like nothing happened).
Fixed a few minor visual glitches.
Fixed a frame rate hitch every 1.6 seconds, seen only on low-end systems that did NOT have any game controllers connected.
