Please take a look.

Description:
Fix charm for jujucharms.com use

- Merge work from mews to support exec.d directory and relative file
paths. Add tests.
- Merge work from benji to support charmworld option needed by upcoming
gui changes. Make a small fix.
- Fix deploy tests.

Tests are still fragile, but I got them all to pass with the current
branch at one time, and verified manually that the various steps still
work.
