Takes a string returned from a Taglist function call and builds an array of tags.
Adds an AlienTag to the list.
A little regular expression scanner. Looks at the list of tags and returns a new taglist containing those tag IDs that match a regular expression filter.
A self-modifying version of filter_taglist. Excercise caution. Elements in the taglist array that do not match the regular expression are deleted.
Takes a taglist string from a reader and appends it to the array.
