install: add support for building psol from source and setting up for development (#1313)

* adds support for `--psol-from-source` so you don't need binary modules, and `--devel` so you can run our tests without going and getting all our dependencies
* adds submodules for testing: mod_pagespeed, ngx_cache_purge etc
* adds support for running as:
```
git clone git@github.com:pagespeed/ngx_pagespeed.git
cd ngx_pagespeed/
git checkout <branch>
scripts/build_ngx_pagespeed.sh [options]
```
* depends on the scripts @hillsp is working on so that we can just check out mod_pagespeed and ask it to build and rebuild itself
* adds colors to output to make it easier to read

ngx_pagespeed

Build Status

ngx_pagespeed speeds up your site and reduces page load time by automatically applying web performance best practices to pages and associated assets (CSS, JavaScript, images) without requiring you to modify your existing content or workflow. Features include:

  • Image optimization: stripping meta-data, dynamic resizing, recompression
  • CSS & JavaScript minification, concatenation, inlining, and outlining
  • Small resource inlining
  • Deferring image and JavaScript loading
  • HTML rewriting
  • Cache lifetime extension
  • and more

To see ngx_pagespeed in action, with example pages for each of the optimizations, see our demonstration site.
