Add data-inline to SASS/SCSS (close trunk-rs#158)

Allows for compiling and then in-lining SASS and SCSS using a new
data-inline attribute in a data-trunk link tag.

Compiling SASS and SCSS without inlining is still supported.

This commit also fixes several spelling mistakes and updates
documentation to reflect the changes.

A non-squash version can be found at Bernd-L:inline-scss_no-squash,
in case you want to see individual commits or for reverting
individual changes.
