Maven proxy scripts

Loads the current ui repo's  build_environment to get the right maven
path. This version of the script is dumb, it will not look for a local
maven installation.
A slightly better ui build script

- D40 specific (no fallback to mvn 2 or java 6)
- some new targets to facilitate tdd
A script to keep an arch installation relatively clean
Add dispatch and a maven compiler plugin to vim
Don't assume build_environment has been sourced in run-cli
More aliases and paths in config.fish
