Review usage of Basset

[lsjroberts]

Basset is used for combining assets, processing them (via LESS for example) and minification.

These tasks are also commonly handled by other tools (e.g. grunt / gulp). Additionally the LESS compilation is pretty dodgy and in general the whole thing rarely seems to work as expected.

I think it would be better to remove basset and have just a simple way of publishing theme assets to the public directory.
