[Omake] SVN Commit: OMake Build System (Rev. 10233)

[Jason Hickey]

Added autoloading, see bug #651.

The problem has to do with cyclic open commands.  For example, C.om opens Configure.om,
and vice-versa.  This fix performs eager linking, but files are loaded only when
their values are dereferenced.  [Also: need to force all opens before building a project.]

Also added a "select" command.  This is intended to allow files that are configured for
multiple versions.

The select is based on Python's "future" directive, where parsing is conditional on
a specific Python feature.

Configure.om gives the following example.

   select feature
   case strictscope
       open build/C
   default
       open build/Common

Unlike other constructs, the indentation does not specify a new scope.  This is more
like an #ifdef.

Also, I'm willing to consider other syntaxes and/or concepts.
