Updated default task, watch tasks, scss compiling and cleaning tasks


1. Added component install to default task.
2. Removed the install task.
3. Added clean task. This will remove a bundles dependencies and build dir. Boot by default.
4. Updated the scss watching task and sass task.  (Was creating a *.css file instead of <filename>.css)
5. Updated the css, js and scss watching tasks to build boot files.

Got the latest grunt-component-build
Ignored components dir inside of boot, not boot itself.
