Changes to the PropertiesSet class which give a choice between storing the 

properties in memory or always reading from the .pro file.  Removal of the
.pro file from the executable (now it MUST be included with the executable).

Typical improvements are 38% less memory usage and 46% reduction in
executable size.

Changes to all 4 frontends to accomodate changes made to the
PropertiesSet class.
