refactor(repeatParser): move to the utils module

repeatParser is not really related to the dropdown module.
So we're moving it, also to make it more accessible to other
modules willing to use it.
Merge branch 'hotfix/repeatparser-extraction' into development
Merge branch 'hotfix/repeatparser-extraction'
refactor(docs): add version number to home

Also made it more responsive
feat($$position): create new $$position service

Allow for positioning elements relative to others. Much like
jQuery UI .position().
fix(dropdown): use $$position to place option list

The option list should have position: fixed, what required the use
of the $$position service.
Merge branch 'development'
chore(release): release 0.3.3
Merge branch 'master' into gh-pages
chore(release): docs release v0.3.3
