Better way to handle EE comments within quoted strings

also updated readme
tag attributes too loosely defined and would highlight comments in EE tags
Special highlighting for known parameters of EE tags
properly delineate end of complete tag name
properly tag EE comments within EE tags
highlighting for EE global variables (site_name, user_name, etc)
refined support for EE globals highlighting
allow EE tags to contain other EE tags
recognize EE tags and comments within PHP
recognize EE tags and comments within JS
support CSS highlighting
ee comments before ee tags
use external support for jquery

removed long block of jquery code which did not work as well as relying
on external jquery package. now requires jquery package installed. if
jquery not installed an error may appear in console when sublime text
starts up, but syntax will fall back on basic javascript
better keyword names

plus initial definition for EE keywords
added support for conditionals and logical operators
refined keyword matching
refined scope names, removed redundant DOCTYPE handler
terminology
major overhaul.

recognize deprecated EE tags and mark as invalid, recognize built-in EE
adddon tags. many scope adjustments for better and more specific
highlighting
improved and consolidated primary code
