boost 6.x-1.15

Known Issues:
#629682: Error message on new install. - Annoying bug that does not effect how boost works.
#631452: Table doesn't exist in multisite setup
#630174: warning: md5() expects parameter 1 to be string, array given in /site/sites/all/modules/boost/boost.module on line 1921

This should be an awesome release. Please report any bugs or WTF's you encounter.

Notes:
I was able to identify a bug with the FieldAPI so the beginning part of the buttons on the boost page have a number added to them as a way to get around the bug; or at least identify when Drupal is screwing up, and prevent the wrong operation from taking place.
The flush button will now say flush or expire based on your settings. If that page is already expired then it will always say flush.
You can now leave the url_alias option turned on in the crawler and it will be smart about what url's it crawls.
Multi site flushing works a lot better now.
301 redirects are now killed from the cache (404 & 403 where already taken care of).
Overwriting of the cache is no longer required for "Do not flush expired content on cron run, instead recrawl and overwrite it" to work. This BTW is a huge win for performance.

Bug Fixes:
#621668: Large Websites & boost_tree_directory() function don't play along
#621870: Set time limits when dealing with the file system
#623784: Gzip corruption when saving data-stream if using pressflow and built in cache and boost at the same time
#623578: boost_stats.php & drupal_json missing
#623516: Based on settings have flush button say flush or expire
#623536: Expiration validation (be smart in short)
#624026: Make the "Flush all sites caches in this database (singe db, multisite)" work better
#625014: boost_cache_kill() is very database intensive
#625962: _boost_index_exists should grab Column_name instead of Key_name
#626634: Call time pass by reference...

Feature Requests:
#623540: Allow setting of url import bulk size
#478644: Cache file path shouldn't be stored in the DB by default
#613926: Better url_alias behavior in crawler
#627844: Kill old paths from cache if a 301 was given
#629470: Set boost tag in header
