Strangecase

===================

* Lots more tests, including entire site building tests.
* Lots of fixes - thanks, tests!
* configurator methods can now offer some special properties that are picked up
in the `strange_case` function, `meta_before` and `meta_after`:
1. defaults - a dictionary of configuration key/values
2. require_before - a list of config keys that must be present when
configuration starts
3. require_after - a list of config keys that must be present when
configuration ends
4. on_start - a function that is called before the root node is created, it is
passed the config dict
5. on_finish - a function that is called after the site is generater, also
handed the config dict

====================

* The configurators have been totally broken up into components, with some of
them being relegated to "extension" status (`setdefault_title`,
`order_from_name`, `created_at_from_name`) and added some new ones
(`file_mtime`, `file_ctime`, `strip_extensions`).
* Opened up the strangecase chat room on irc.freenode.com. Join us! :-)
* Moved `url` and `iterable` "detection" into configuration. *However*, there
**is** still a `url` method on `Node`, which attaches the parent's url.
* Tests! Finally added a test framework, using py.test.

===================

* refactored the extensions folder, but that shouldn't affect anyone

* added 'default_type' config, used when `type` isn't set and no `file_types` match the file

===================

* added scss_processor and clevercss_processor. They compile and save SCSS/CleverCSS into CSS.

* moved all extensions into the strange_case.extensions module. processors, extensions, and filters
are all imported from there.

* refactored configurator to use the 'file_types' config, which is modified during startup by
processors to associate file types with a default processor. this replaces the `dont_process`
configuration.

* updated README to reflect these changes

===================

* added a `paginated` processor. it will iterate through all the pages in the folder and
create a `Page` object that holds `paginated.limit` items (default: 10). the first page
will be named after the page that you assign `type: paginated`. every page after that
will be named "pageN.html", where N is one-indexed (and therefore starts at "2", since
the first page is probably "index.html"). see the README or `processors/paginated.py`
file for more info

* added favicon.ico to list of dont_process defaults

* command-line options (`-x`, `--exclude`) to exclude folders from the `--watch` command.

* date configurator matches Y, Y-M, or Y-M-D. month and day default to 1.

===================

* you can now specify the following configurations as command-line options:
+ `-p`, `--project`: project_path
+ `-s`, `--site`: site_path
+ `-d`, `--deploy`: deploy_path
+ `-r`, `--remove`: remove_stale_files
+ `-n`, `--no-remove`: remove_stale_files
+ `-c`, `--config`: config_file
+ `key:value`: any key/value
+ `key: value`: these don't have to be "touching"

These override any defaults, and any settings in config.py and config.yaml

* You can now have python configuration front matter. Instead of dashes, use "\`\`\`"s
python configuration front matter is eval'd with the current `config` as `locals()`,
so any assignments you make in you front matter will be available in your template.

See README for more information

* Added `config_hook`, so that you can assign configuration *at the end* of configuration.
It is a callable that is passed one argument: the `CONFIG` variable.

You can use this to process configurations that are expected from the command line.

* Fixed the file removal to use absolute paths when matching against `dont_remove`, but
outputs using `os.path.relpath`

* Terminal-formatted output, and writes messages to `sys.stderr`

* Support error messages using `assert` in config.py.
