[DrJava] Committed version; ready for release?

[Brian S. <bs...@bs...>]

I just tested that the new configuration framework preserves the ability
to let the user pick a compiler at startup if none is found. It works
fine, but there was a problem that caused the UI to not be correctly
updated with the list of compilers. (This was caused by reordering the
construction of MainFrame in DrJava.java, which I fixed and put in a
comment explaining.) I committed these changes.

With this out of the way, does anyone know of any impediments to doing a
release soon? If the line enumeration is going to be stable soon enough,
we can wait for that. Anything else?
