RT-win32 3.0.11-pre1

I’m happy to announce the first prerelease of RT-win32 3.0.11:

MD5 (rt-3.0.11pre1.exe) = 373ab2ddccc0da2248c388722a8cabad

It is based on the rt-3.0.11-final codebase. There are no significant
changes over RT-win32 3.0.10; the Edit UIs of TabbedUI are speeded
up quite a bit, some inconsistent Add/Edit semantics was fixed, the
experimental Atom/0.3 interface is included – and that’s pretty much it.

If no problems are reported for the next week, I’m going to declare
it RT-win32 3.0.11-final.
