Store adjoint solutions in SolutionHistory

Patch from Vikram Garg to store the results of transient adjoint
solves
Add a flag to SolutionHistory

Allow code to specify whether store() overwrites previously seen data
MemorySolutionHistory updates

Respect overwriting flag when storing; avoid "running off the end of
stored data" when retrieving.  Based on a patch from Vikram Garg.
More flexible MemorySolutionHistory

By checking our saved times against system time we no longer assume
that we're always going forwards in time when storing and backwards
when retrieving.
