Sass

- [ ] Ready to merge

TODO LIST

- [x] Implement sass/scss without compass
- [x] Implement sass/scss with compass
- [x] Implement Bourbon
- [x] Implement Blueprint (not implementing at the moment as it's outdated and will eventually evaluate if there will request about it, I wrote the procedure how to implement it)
- [ ] Implement other frameworks or libraries
- [ ] Timeout the processors
- [ ] Debounce the processors
- [ ] Rename `port` in `address`
- [x] Check how `@import` works - All ok. for sass file use `@import 'xxx.1';` or `@import 'http://jsbin.com/xxx/1.scss';`; for css use `@import 'http://jsbin.com/xxx/1.css';` Using the jsbin url for sass import will let us put the files in different physical locations without any problem
- [x] Standalone css version of scss/sass panel
- [x] Send compiling errors
- [ ] Add metrics
- [x] Write readme for sass
- [ ] Better parsing of the errors (probably not split per line as the format seems not consistent)
