version naming for extras apps

[Allison Randal]

A quick note, so anyone can comment.

In ARB apps, we're getting some non-standard version numbers in packages 
like 1.0-maverick1 or 1.0-0extras1. We would like to set a standard and 
stick with it.

Following some discussion on #ubuntu-devel, it seems the best option is 
to use no modifier (i.e. 1.0-1). Because extras packages install in 
/opt, they'll always be built custom for Ubuntu, and there's no need to 
distinguish packages that are or aren't synced from Debian.

Sound workable? Any concerns?
