Add "test" to run Hush tests

This replaces the hack that was test.sh with a more extensible and less hackish
test script.

To run the tests just run "./test" . By default it shows all RPCs called via
the "--tracerpc" flag. If you want to set custom test flags you can do

TEST_FLAGS="--elite-test-flag --foo" ./test

Currently we are only running lockzins.py and shieldcoinbase_donation.py tests
which are hardcoded. The plan is to allow custom sets of tests to be run with
this script.
