T. Joseph Carter a3d67123cc Removed a2cScriptURL and renmaed .txt from scripts
Replaced downloading scripts and files from a2cScriptURL with
installation from the source tree.  This obsoletes a2cScriptURL, so it's
been removed.

It made sense to remove the .txt from the script names since I was
rewriting the lines that use them anyway.
