Use general custom definers rather than :definer

Browse Source 
The former approach was the cause for a huge increase in startup
time (adding ~0.4s) when :leader and :localleader were used. This is
because general-define-key was called for every key-def pair.

This new approach batches these calls, which has decreased the
performance impact by at least 80%.
