Removed an inefficient preg_match regular expression used when capturing data in lists
Replaced assign_variables() with a simple regex to match stash variable pairs when setting lists
Account for list rows where the variable pairs do not exist
Replaced assign_variables() in _parse_template_vars() with a more efficient regular expression. Tweaked the stash tag pair regex to match empty subsequent empty pairs
Corrected a bug in the regex that matches single stash variables
Fixed a bug when using backspace in lists where the string to be removed contains a RD. Improved passing of stash embed variables to extended templates. Improved html compression now trims surrounding whitespace. Compression and other formatting functions can now be used with static caching.
Bumped to 2.5.9
