This PR removes the Python 3.4 tox task and updates references in the
code to Python 3.5+.
tox complains about Python 3.4, which is EOL after next month:
> py34 installed: DEPRECATION: Python 3.4 support has been deprecated. pip 19.1 will be the last one supporting it. Please upgrade your Python as Python 3.4 won't be maintained after March 2019 (cf PEP 429).
Specific options passed to pandoc2 in order to get similar results than
with pandoc1:
- Disable smart quotes from the markdown output.
- Enable raw parsing from html.
Competing static site generators integrate the functionality of regenerating
content and serving it into their main executable. In pelican this
functionality used to be in an external script `develop_server.sh` which
resides in the blog base directory. This has the disadvantage that changes in
pelican can break the `develop_server.sh` scripts which will not automatically
be upgraded together with pelican by package managers. Thus, pelican should
integrate this functionality into its main executable.
To this end, this commit removes `develop_server.sh` and adds three command
line options to the pelican executable:
* `-l/--listen` starts the HTTP server (`-s/--serve` was already taken)
* `-p/--port` specifies the port to listen at
* `-b/--bind` specifies the IP to bind to
`--listen` and `--autoreload` can be used together to achieve the same
effect that other static site generators offer: Serve files via HTTP
while at the same time auto-generating the content.
Since the `develop_server.sh` script was removed, pelican-quickstart looses the
`develop` option.
Since the `develop_server.sh` script was removed, the Makefile looses the
`stopserver` target and the `devserver` target is replaced by running `pelican
-l` in the foreground.
Since pelican now offers the `--listen` option, the fabfile uses that instead
of starting the socketserver itself.
- Use the jinja2 templating language for Makefile, fabfile,
pelicanconf, publishconf, and develop-server.sh
- Add logic in pelican_quickstart.py
- Let jinja2 handle opening and reading template files
- Remove thus unused functions for string.Template

For my own blog this means it doesn't break during import, but I don't know pelican well enough yet to say if this is correct or not.
