Update translations from Transifex:

 - Chinese (traditional)
 - Japanese
 - Romanian
 - Ukrainian
Updated LAV Filters to 0.61.1-5-2fcf5d4 (custom build based on stable version 0.61.1)

Important change:
 - LAV Splitter: Fix the opening of some Blu-ray discs which would take several minutes and could hang the player.
Support for opening "icyx://" stream URLs.

LAV Splitter can handle them now.
PGS/DVB subs: Enable auto-fit logic only for HD contents.

SD contents are often anamorphic and thus break the auto-fit logic. Auto-fit is mostly useful for HD subtitles used on cropped or resized video anyway.
