[Develop] next version for trunk

[will]

We're currently using the trunk for post 1.0 development and the 1.0 
branch for 1.0 maintenance (and possibly features that will land in the 
1.x timeframe--we'll see what happens).

Anyhow, someone opened up a bug:

http://bugzilla.pculture.org/show_bug.cgi?id=9216

asking us to bump the appVersion number in trunk.

I'm going to bump it up to 1.5.  We can always adjust it.  I'm not 
really sure what it affects other than logs and read-outs and such.

Anyone think this is a bad idea?
