Support temp triple store wrapped by a BigdataSail

[thompsonbry]

For example, by adding the following constructor:

public BigdataSail(final AbstractTripleStore database, final AbstractTripleStore mainDatabase) { .... }

The change should be applied to both the 1.0.x branch and the new 1.1x branch.

This ticket is also a request for a 1.0.3 release with this feature.

Added alternative constructor for the BigdataSail? which may be used to wrap a TempTripleStore? as a SAIL by also passing in the AbstractTripleStore? instance for the main database residing on the Journal or IBigdataFederation. That reference is used to resolve the QueryEngine?.

Committed revision r5750.
