Change regular expression excerpt matching beta feature to use strings instead of regex
In the ME admin tool there is a "Regular Expression To Match For MultiExcerpt-Include" setting:
This is for a beta feature that allows you to include other macros besides just multiexcerpt macros.
If a user sets the value to a very generic regular expression, like ".*" then they can break many of their includes. General regex's can lead to unpredictable behavior.
Change this feature to use hard-coded strings. Perhaps the "Regular Expression To Match For MultiExcerpt-Include" setting could be changed to "Other Macros to Find for MultiExcerpt Include" and it could be a comma-delimited list.
