various menuselect fixes as a result of boredom during a 9 hour flight and 

now a 9 hour layover ...
- If a module is disabled from being built because of failed dependencies or a
  conflict, automatically re-enable the module if the issues are later
  resolved.
- If a module has been disabled by default, only set this value if there is not
  an existing menuselect.makeopts file.  Previously, this value would get reset
  every time you ran menuselect.
- staticize a bunch of functions and variables that aren't public
