MicroView 2.5.0 rc1

We're happy to announce the availability of our first release candidate of MicroView 2.5.  After some 22 beta releases and 31 alphas and after lots of great feedback from our user community it's high time that we release 2.5.0 final.  Unless there's major issues with this release candidate, one can expect this to become the final 2.5.0 version in a few weeks.  We'll continue to add new features etc. but this will occur in a post-2.5 release.
