Some captions parsing issues (v4)

[jeroen]

There's a few small issues with parsing V4 captions:

• Carrier returns in TT files show up as double breaks in the display.
• In fullscreen, the captions are placed over the controlbar
• SRT files with additional breaks are parsed incorrectly.
• If there's no caption, the back area still shows.
• Last, the CC dock could use a slightly cooler graphic ;)

• Fixed carrier return issue by adding a regex to filter them.
• Fixed captions-over-controlbar in two ways:
  • First, the captions are not mouse enabled anymore.
  • Second, the captions are placed above the controlbar if controlbar=over or fullscreen=true
• CC dock icon is replaced with a slighty more squarish graphic.

The SRT issue cannot be fixed, since the parser needs double linebreaks to detect a new caption. I guess that's the downside of using a textformat. It can be worked around by a single space on the extra lines though. Here's a short example:

3
00:00:13,500 --> 00:00:15,000
Are you?

4
00:00:17,000 --> 00:00:20,000
Violet, please!
- I am not your babe!
  
  
  

5
00:00:24,000 --> 00:00:29,000
You stupid cow,
look what you gone and done now, ay.

(copy-paste the SRT block to see the space that's on the 3rd / 4th line of caption 4).
