bump version to 0.7.0 (#158)

It's been a little too long since we bumped the version, so there's a
bunch that's new in 0.7. New commands since 0.6:

- "humility doc": print command documentation
- "humility extract": extract all or part of a Hubris archive
- "humility flash": flash archive onto attached device
- "humility gdb": Attach to a running system using GDB
- "humility hash": Access to the HASH block
- "humility openocd": Run OpenOCD for the given archive
- "humility registers": print Hubris registers
- "humility spctrl": RoT -> SP control
- "humility validate": validate presence and operation of devices

Also of note:

- The old "humility renbb" has been renamed "humility rendmp" 
- We have a trycmd-based test suite thanks to @steveklabnik
- We have many Hubris core files added as fodder for testing

Beyond these, many bugs that have been fixed and features added to
various commands; of note in particular is that "humility dashboard"
(and anything else that purely makes HIF calls) will not halt the
target -- which should make it significantly less disruptive.
