A support for the Switch Construct
Add support for switch statemens in FromCore
Update travis config to support branches

The travis config is updated to support building other branches than master
of feldspar-language.
With this change travis will clone the feldspar-language repository and
then try to check out a branch with the same name as the current branch in
feldspar-compiler. If that fails we will check out the master branch.
Typo
Tweak travis config
More Travis tweaks
Merge branch 'master' into switch
Follow the change in argument order for `switch`
Update test to use parameter
Remove unnecessary imports
Merge pull request #121 from Feldspar/switch
