Dynamic import/merge bootstrap and CLARIN style extensions

[Twan Goosen]

Currently (with 4.0 in development) the bootstrap based CLARIN styles are fully included with the VLO sources. It would be better to do the following build time:

• retrieve (via Maven?) and extract the bootstrap less sources
• retrieve (via Maven?) CLARIN's customisations (variables.less and potentially some kind of clarin.less) and put these in the right location
• include the core bootstrap and clarin customisations from the VLO's main less file and compile the less using a Maven plugin (this already happens in the current development branch)

When this is in place, the copies of the bootstrap sources and CLARIN customisation/override file(s) can be removed from the VLO sources.

See ​base_style #3 on GitHub for details on the packaging and distribution of the CLARIN style.

Possibly ​wicket-bootstrap-less can be helpful

Style now maintained in and available from ​base_style repository on GitHub. ​Issue #4 covers Maven distribution of the style (compiled + less sources).
