Use cgetfile instead of cfile

[tomtom]

The plugin currently uses cfile to load the quickfixfile into vim. This can be annoying and disrupting. I'd suggest to rather use cgetfile, which loads the quickfix files but doesn't make the cursor move. This way it's up to the users to handle changes in the quickfixlist as they like -- e.g. by defining a QuickFixCmdPost autocommand.

BTW one minor annoyance I found is that the plugin always uses the first gvim server. This can be a problem when users have multiple instances of gvim open. It would be nice if they could define somehow whether they want the sbt plugin to use a specific server.

I'll have to give that a try. At the least it could be an option within the plugin. I'm going to split out the other bit into a separate issue. This is something I've wanted for a while.
