Border standards

With all the possibilities E16 has for borders, what types/names should be considered "the standard set".

Border standards

There are a few that should be there because they are referenced in the code:
DEFAULT
BORDERLESS
DIALOG
ICONBOX
PAGER

BORDERLESS really should be intrinsic, as it should be identical in all themes, but as is it should be defined in every theme.

matches.cfg also references
TRANSIENT
SHAPED
FIXED_SIZE

I see that some of the "core" themes use FIXEDSIZE in stead of FIXED_SIZE in windowmatches.cfg. It really should be one or the other. I think I'd prefer FIXEDSIZE if that doesn't break too many themes.

Other than that things have been entirely up to the theme, and I don't really have an opinion about what would be an appropriate standard set.
