Delta parceling, valid types bugfix, INSERT parsing.

Made EntityDelta and ValuesDelta directly Parcelable to
pass across configuration changes.  Moved the re-parenting
code to separate EntityDelta.mergeAfter() method.  Fixed
getValidTypes() bug that didn't handle typeOverallMax
in "unlimited" cases.  Wrote INSERT parsing code to merge
incoming extras bundle into a new or existing EntityDelta,
also handles any source constraints.

Initial hook-up of edit UI to persist changed data, only
shows first Entity because not connected to tabs yet.
