Batch Update Improvements

-Npc Ids: Write out a properties file with all the shifts that happened. Can be used later for a script to auto update scripts with those results
-Text Ids: Ability to write out the filtered dialog tables (post reg-ex stripping). Can be used to help find compatible strings for Text ID lines that have bad character problems
-Text Ids: Ability to manually specify a global search string to try for a variable if all else fails. Helpful for things in every file like ITEM_OBTAINED, etc
-Text Ids: Fix bugs with searching the reg-ex filtered table.
