Fix Freelook on Linux and add speed reset.

Should fix issue 7692.
Also fixes issue 7147.

I have no idea if these changes will affect Mac or Windows users, so please test.
Update freelook description.
Updated game ini files
Explicitly compile external WX in C++11 mode.

Apparently an update to gcc now requires this.
Changed the hotkeys to 1 and 2. Message in GUI changed to reflect this.

Freelook fixes
Android: Use a PagerTabStrip instead of the ActionBar.

The ActionBar method of doing the tabular layout is deprecated on Android 5.0.
This method alleviates those deprecations while providing the same functionality.
Make freelook hotkeys configurable.

Make freelook hotkeys configurable.
Rewrite FileSearch and improve ScanDirectoryTree.

- FileSearch is now just one function, and it converts the original glob
  into a regex on all platforms rather than relying on native Windows
  pattern matching on there and a complete hack elsewhere.  It now
  supports recursion out of the box rather than manually expanding
  into a full list of directories in multiple call sites.

- ScanDirectoryTree returns the parent entry rather than filling parts
  of it in via reference.  The count is now stored in the entry like it
  was for subdirectories.

- .glsl file search is now done with DoFileSearch.

- IOCTLV_READ_DIR now uses ScanDirectoryTree directly and sorts the
  results after replacements for better determinism.
Fix CopyDir to not require source and dest paths to end with "/".
Disable some stuff in IPC_HLE when determinism is required.

This includes net, which is nonsensical to "sync" in netplay/replays
(could have the host do the Wii networking in future though...), and USB
keyboard, which just needs some love to do the same.
Disable /dev/usb/hid too.
