Feature: Added keymap toggle for EasyGrepSearchCurrentBufferDir
Fixed: command line parsing of Grep command discarded spaces
Feature: added support for grep exclusions when grepprg is grep or ack
Feature: Added EasyGrepDefaultUserPattern option.  Thanks to Jesus Barcons for the suggestion.
Improved: Cleaned up the documentation
Improved: Cleaned up the internals of the script substantially
Improved: Formalized multi-select mode, which is when multiple file extensions are selected from the options explorer
