Mike Bayer 10dbde43db - The per-dialect cache used by TypeEngine to cache

dialect-specific types is now a WeakKeyDictionary.
This to prevent dialect objects from
being referenced forever for an application that
creates an arbitrarily large number of engines
or dialects.   There is a small performance penalty
which will be resolved in 0.6.  [ticket:1299]

base

WeakCompositeKey was coded incorrectly and was not weakly referencing anything. However when repaired, the usage within RelationLoader._create_joins() still creates cycles between key elements and the value placed in the dict. In the interests of risk reduction, WCK is now removed and the two caches it was used for are now non-cached. Speed comparisons with one join/eager-heavy web application show no noticeable effect in response time.
