Updated LAV Filters to 0.60.1-9-0b641ef (custom build based on 0.60.1-4-d7a05e7)

Important changes:
 - LAV Video: Fix a crash when trying to decode WMV-3/VC1 with the DMO decoder unavailable (fixes #3929).
 - LAV Video: Fallback to avcodec for WMV3/VC-1 if the DMO decoder is not available.
Add a Croatian translation.

The composition of the translation team can be found on Transifex: http://www.transifex.com/projects/p/mpc-hc/language/hr/members/.
Change default settings:

- Add hotkey for navigation panel (CTRL+9)
- Enable hiding docked panels in fullscreen mode
Remove interprocess SetForegroundWindow()

Instead, allow existing mpc-hc window to take focus from WM_COPYDATA
sender.
Make caption-less drag take priority over LDOWN

Again.
