Ruby VM measurements

The Ruby agent now records more detailed information about the performance and behavior of the Ruby VM, mainly focused around Ruby's garbage collector. This information is exposed on the new 'Ruby VM' tab in the UI. For details about what is recorded, see:

Separate in-transaction GC timings for web and background processes

Previously, an application with GC instrumentation enabled, and both web and background processes reporting in to it would show an overly inflated GC band on the application overview graph, because data from both web and non-web transactions would be included. This has been fixed, and GC time during web and non-web transactions is now tracked separately.
Fixes the wrangling of multiple tags at once

Another issue that keeps on giving: http://code.google.com/p/otwarchive/issues/detail?id=3911

Also:
* tags on the Tag Wranglings pages (aka mass bins) can now be wrangled to multiple fandoms at once, to mitigate the problem of crossover tags being put in only one of the fandoms
* more notice and error messages where needed and appropriate
* obliterates tabs and turns them into spaces
* changes hash syntax from rocket (=>) to colon (:) where I had already changed some rows
* changes " to ' around Ruby strings where possible (i.e. no interpolation in the string) (you have Ariana to thank for that ;P )
More fixes to mass wrangling

http://code.google.com/p/otwarchive/issues/detail?id=3911

* Use ```where``` instead of ```find_with_ids```, which is missing from this Rails.
* Make the various things in the controller a bit more separate

The tag wrangle action is more verbose than the tag_wranglings index: it lists the successful changes as well as the errors. This was on purpose, but can be changed if needed.
