Add parsing support for gift transactions (Schwab Equity Awards JSON).

This adds a new action type, as TRANSFER seems to deal with money transfers
rather than share transfers, and SALEs also involve money whereas gifted
shares do not.

The calculation code will raise a NotImplementedError if it encounters
one of these transactions.

This may help #510. This contribution has been developed in my spare time.
