git-core
ruby-dev
node.js
compass
bootstrap-sass
grunt
Add ruby bundler
Add sudo to gem installations
Create Compass project
Add provisioning for web development stuff
Add .sass-cache to .gitignore
Merge branch 'develop' into bootstrap-template
Add first steps of bootstrap layout
Add sudo to compass install command

That was just wrong.
Merging changes to disable caching in development
Fix installation of gems and compass

These changes have been made:
 - Add user_install=no to gem installation as per suggestion by @joharohl
 - Add ignore_errors: True to compass installation. Without it provisioning fails when files exist (although installation seems to work). This is an ugly hack however, since other errors will also be ignored.
