[REF] *: convert less content to scss content

Convert content so that the assets compile on app installation. The
style is still broken after this as the variables/mixins/... are not
defined in the right order (as it did not matter in LESS but does in
SCSS).

This commit basically changes:
- Variables: @​var_hello -> $var-hello
- Mixins: .mixin_world() {} -> @​mixin mixin-world {}
- Classes used as mixin: .my_class() -> @​extend .my_class
    - Here there were no other solution than to convert the use of
      a mixin call by the use of an extend as a first approximation
- LESS functions -> SCSS functions (e.g. fade -> rgba)
- Move first variable definition before the variable is used
    - Still need to make sure last variable definition is at the
      right place
