WINTERMUTE: Preserve const when handing chars over to drawText
WINTERMUTE: Add clarification comment in loadSubtitles
WINTERMUTE: Turn display() and update() into void functions.

No idea why they were bools in the first place.
WINTERMUTE: s/uint32 _lastSample/long _lastSample/
WINTERMUTE: Turn a bunch of uint into uint32 in VideoSubtitle
WINTERMUTE: Rename VideoSubtitle to SubtitleCard
WINTERMUTE: Use full braces for blocks in Videosubtitler
WINTERMUTE: Avoid doing check before delete (deleting 0-pointer is safe)
WINTERMUTE: Rename VideoTheoraPlayer->_subtitles to _foundSubtitles for clarity
WINTERMUTE: Lose unnecessary if() in VideoTheoraPlayer
WINTERMUTE: Introduce BaseGame->expandStringByStringTable(&Common::String)
WINTERMUTE: Don't bother inheriting BaseGame in SubtitleCard
WINTERMUTE: Remove useless constructor from SubtitleCard.
WINTERMUTE: Const'fy members of class SubtitleCard
WINTERMUTE: Use BaseGame->expandStringByStringTable(&Common::String) in SubtitleCard
WINTERMUTE: s/delete array/delete[] array/
WINTERMUTE: Use int32 for _lastSample in VideoSubtitler

We are thus making room for the sentinel == -1
WINTERMUTE: Initialize tokenSomething vars in VideoSubtitler

MSVC complains otherwise.
WINTERMUTE: Turn _subtitles into Common::Array<SubtitleCard> in VideoSubtitler

This necessarily loses const in SubtitleCard's attributes
WINTERMUTE: new char[str.size()+1] in BaseStringTable::expand

This makes room for the EOS char.
