Improve the dialog for subtitle encodings selection.

Prettify the dialog by moving the option for unicode subtitles up,
and place it below the subtitle encodings combo box.

In this way, everything related to subtitle encodings is grouped
together.

As a result, we'll need the label unconditionally.

Prettify the dialog for subtitle encodings selection.

Use the existing unicode encoding help message for the
sake of consistency.

Add option 'sub_utf8' to the GUI configuration file.

UTF-8 subtitles couldn't be set without iconv using the GUI so far.

Additionally, update man page.

Add support for files with MLTI chunks.

Fixes 06.rm and 08_lect_01.rm from FFmpeg trac #2152
Fixes also files from ftp://ftp.aduni.org/videos/


The patch has these limitations:
 - no multirate files with MLTI chunks
 - no mixed files (eg. MLTI for audio but not for video)
 - no MLTI for video together with non-ra audio (eg. ralf)
 - only DATA v0 (no v1, versions greater than 1 should not exist)
Files with these feature shuld not really exist anyway.

Also video MLTI files with only one stream are supported but untested
