The largest new feature is that it is now possible to include other
files into the RML by using the "include" tag. This is useful for making
markup files more modular.
Also added some more options for existing things (e.g. built-in detail
options).
In other words, a pilot can only be used in the same language it was
created with. Checks both the initial selection screen and in the
barracks.
Also fixes issue with PLR version being ignored in pilotfile::verify()

MASSIVE thanks to Mjn.Mixael and Blue Planet for tireless constant testing.
(It's still not perfect, but it probably wouldn't be where it is at without them)
Spans a lot from initial commit to AP Branch in r6835.
