[photran-dev] Message Bundles

[Jeffrey Overbey <overbey2@xxxxxxxxxxxx>]

Photran is almost entirely converted to use message bundles.  I need to 
add info about this to the Developer's Guide.

I am waiting to commit the changes to the photran.ui.vpg project since 
Mariano has a number of changes out.

The only project I will not be able to convert is photran.core.vpg.  
There are a few outstanding patches on that project, and it contains 
generated code... also there are more than 1,000 literal strings... so 
that's more than I can deal with this late in the game.  Luckily, not 
externalizing it will only affect a few error messages and some of the 
UI for refactorings.  The vast majority of the UI is (obviously) in the 
UI plug-ins, which are externalized, so I think this will put us in good 
shape for Helios.
