scriptharness 0.2.0

[escapewindow]

I've been getting some good feedback about scriptharness 0.1.0; thank you. I listed the 0.2.0 highlights and changes in the 0.2.0 Release Notes, but wanted to mention a few things here.

First, mozharness' config had the flexibility of accepting any arbitrary key/value pairs from various sources (initial_config, commandline options, config files...). However, it wasn't always clear what each config variable was for, or if it was required, or if the config was valid. I filed bug 699343 back in 2011, but didn't know how to tackle it then. I believe I have the solution now, with ConfigTemplates.

Second, 0.1.0 was definitely lacking a run_command() and get_output_from_command() analogs. 0.2.0 has Command for just running+logging a command, ParsedCommand for parsing the output of a command, and Output for getting the output from a command, as well as run(), parse(), get_output(), and get_text_output() shortcut functions to instantiate the objects and run them for you. (Docs are here.) Each of these supports cross-platform output_timeouts and max_timeouts in both python 2.7 and python3, thanks to the multiprocessing module. As a bonus, I was able to add context line support to the ErrorLists for ParsedCommand. This was also a want since 2011.

I fleshed out some more documentation and populated the scriptharness issues with my todo list.

I think I know what I have in mind for 0.3.0, but feedback is definitely welcome!
