Module documentation

I have changed the syntax for module definitions; here is the one for concurrency to demonstrate the new syntax. Note that you can now specify a main help article for your module, and I encourage everybody to document their modules now:

REQUIRES: contrib/dlists contrib/serialize contrib/match ;

PROVIDE: contrib/concurrency
{ +files+ {
  "concurrency.factor"
  "concurrency.facts"
} }
{ +tests+ {
  "concurrency-tests.factor"
} }
{ +help+ { "concurrency" "concurrency" } } ;

What Factor is missing now is a nice graphical tool to browse modules, load them, run their main entry points, jump to module documentation, and jump to source files making up the module. This will come in 0.86.
