search_and_replace 5.x-1.1

This adds a lot of new funcitonality to the search and replace module. No one was really asking for it but...I figured it would help make the project even more useful so I added the following features:
* Ability to perform either a search or a search-and-replace on node titles, bodies or both
* Case sensitive and insensitive searching
* Select All Types button to speed up type / replace selection (degrades away nicely)
* Trap for typing nothing in the replace field that requires you to type %NULL% if you plan on truly replacing a search string with nothing
* Creates a revision for each replacement as well as a Log message saying the module made the change to the node and what term replaced which
