Remove modules
For a test site for CS + TTORP

 * includes ircmaxell/password-compat for new cs-webapplibs stuff
 * change location of shared TTORP stuff (now in "/vendor/crazedsanity/cs-battletrack/..." instead of "/lib/cs-battletrack/...")
 * minor comment cleanup
 * some changes to keep authentication backwards-compatible: once CS has a "lost password" system, an email can be sent to each user telling them to reset, thus utilizing the newer more secure system.
