Note: The large jump in memory usage here is due to that the benchmark
is blocking the main thread, so at the end there are ~100 video frames
waiting to be displayed.
This eliminates the need to explicitly delete the parsed blocks.
Also go ahead and remove AssDialogue::Blocks since it's really not a
very good idea in general.
Mostly just bugs in unreachable code and stylistic things, but there's a
few incorrect reachable things that were working by coincidence and
gratuitous dynamic_casts.
Split the configuration dialog off into its own file and mostly decouple
it from the subtitle format.
Save last used export settings to options and restore them the next time
the dialog is opened.
Use libaegisub for charset conversion and IO rather than wxWidgets.
Use libaegisub's line-wrapping logic and finish implementing all of the
various wrapping modes.
Make unchecking the "Translate alignments" checkbox do something.
