- Remove gratuitous Unixisms so that fabfile will work on Windows
- Docstrings for tasks so `fab --list` is more useful.
- Add `gh_pages` task for publishing to GitHub Pages
using [ghp-import](https://github.com/davisp/ghp-import)
Because Pelican always rewrites all output, the mtimes always change, so
rsync would always transfer all the files which defeats the purpose of
rsync. The '-c' option (--checksum) compares the checksums rather than
mtimes.
Previously `ctrl+c` a `fab serve` wouldn't necessarily terminate the web server. Even if it does, re-using the command `fab serve` might result in the following error:
```
socket.error: [Errno 48] Address already in use
```
This fix manually creates a `TCPServer` with `allow_reuse_address` set to `True`, which solves this issue.
Tested on OS X 10.9.1.
This commit adds optional fabfile.py generation during the
pelican-quickstart process. Reasons include:
* "make" is cumbersome to install on Windows
* Fabric runs in any Python environment
* fabfile is just Python and thus more flexible and extensible
This is an initial implementation and does not currently provide as many
upload options as its Makefile counterpart.
Refs #584.
