Use a temporary directory for Jekyll data to avoid modifications to src contents when injecting

[ferrarimarco]

Currently the inject:head and inject:footer tasks work directly with src/_includes/head.html and with src/_layouts/default.html.

This leads to source code modifications after each build.

A solution to this issue (that I implemented in my gulp file) is:

1. Serve assets from '.tmp/serve' instead of '.tmp'
2. Copy src contents (minus assets) to '.tmp/jekyll-build'
3. Run Jekyll pointing '.tmp/jekyll-build' in _config.yml
4. Update paths for other Gulp tasks accordingly

EDIT: maybe jekyll-build should be changed to something like src-jekyll-preprocessed to further clarify.

Hmm, that's true and something I hadn't thought of either, but it's not something that I have a big problem with. I'll take a look at it though and see if I can figure out something better :smiley:

[ferrarimarco]

Please look at my updated gulp file. A solution is already in place.

Currently I use three directories in .tmp:

1. jekyll-preprocessed-src: everything to process with Jekyll, after injections
2. jekyll-built: jekyll results
3. assets-built: preprocessed assets (js, CSS, images, favicon)

Sweet, feel free to send PRs for these if you want to. Otherwise I'll tackle then in a few weeks.

The build is already broken, so it's difficult to write integration tests.

Yeah, something is broken in one of the testing packages, not really sure what gives, I'll take a look.
