CMAKE_INSTALL_PREFIX and CMAKE_INSTALL_DATAROOTDIR are now used to resolve the resource path. As of this commit, there are only two paths where resources are searched, under the user home directory and under this install prefix directory (which defaults to /usr/local/share/emulationstation/resources but can be set to for instance /opt/share/emulationstation/resources using the appropriate CMake flags).
If filterTrigger detects a positive axis event on a common trigger axis while also
configuring a trigger, the next input event will be a negative axis press
(as the trigger needs to transition from >0 to rest at -32767).
Filter this negative event or else the next item in the configuration dialog
(typically "left thumb") will erroneously detect this as a separate event.
* Filter axes 2/5 for all devices, but only if LeftTrigger or RightTrigger is being configured. This should fix compatibility with XBox 360 and other generic controllers that use these axes for triggers, but won't affect other controllers using these axes for analog sticks, etc.
* Improve third-party PS3 detection (some Shanwan controllers have a grave accent in place of 'm' for 'Gamepad').
The hid-sony driver has both analog and digital buttons for the triggers,
and the analog values range from -32767 to 32767, which can cause two unwanted
input events (digital button and negative axis) per press.
Implement a function to filter out unwanted input events during configuration,
but isolate detection to known PS3 controllers with 6 axes so that older versions
of hid-sony and the sixad driver (which use 25+ axes) are not impacted negatively.

* add hotkey button gfx and hotkey to input configuration
* prompt user if no hotkey set, and offer to use select
* if no hotkey is set, still save an entry with key id 0, for backward compatibility
