Title: Extend PrtInsert to support multi character action

PrtInsert can be mapped to insert clipboard or some register.
This extends PrtInsert to support insert any register (e.g "b
register).
Rationale: I mostly use " (unnamed register for work) so now
let g:ctrlp_prompt_mappings = {
\ 'PrtInsert("r\"")': [''],
\ }
will work.
( when user enters c-u the content of unnamed register is entered)
