There are two solutions I can think of for this.  The first is to bypass the 
hg executable and directly use the internal function calls to get the diff 
data.  This idea is discounted right away because 1) internal APIs change
over time and I don't want to have to support more than one version of
them   2) You probably don't buy much performance gain by using Mercurial
that way  3)  Some Windows users will only have hg.exe installed, so qct
must support that configuration.

The second idea is to run 'hg diff' repo wide at startup and cache the results 
in a dictionary keyed by filename.  The 'Refresh List' button would then 
trigger the back-end to empty it's cache.

I had disabled the multi-selection method earlier because it conflicted with 
the file selection methodology.  I'll take another look at it, it's likely 
this can be re-enabled now.

Thanks for the feedback
