9f55fb668d silenced unpaper, optipng for cleaner output 
moved parser settings to settings
removed forgiving ocr (now default) since tesseract is plenty accurate even without defining the correct language.

b350ec48b7 Mention FORGIVING_OCR config option when language detection fails. 
It is not obvious that the PAPERLESS_FORGIVING_OCR allows to let
document consumption happen even if no language can be detected.
Mentioning it in the actual error message in the log seems like the best
way to make it clear.

f948ee11be Let unpaper overwrite temporary files. 
I'm not sure what the circumstances are, but it looks like unpaper can
attempt to write a temporary file that already exists [0]. This then
fails the consumption. As per daedadu's comment simply letting unpaper
overwrite files fixes this.

[0]
unpaper: error: output file '/tmp/paperless/paperless-pjkrcr4l/convert-0000.unpaper.pnm' already present.

c99f5923d5 Rename parsers to DATE_REGEX 
In moving the `parsers` variable into the package-level, it lost the
context, so a more descriptive name was needed.

5342db6ada Fix pycodestyle complaints 
Apparently, pycodestyle updated itself to now check for invalid escape
sequences, which only complain if the regex in use isn't a raw string
(r"").

8e9d5caa37 Rename .TEXT_CACHE to .text 
Properties should use snake_case, and only constants should be ALL_CAPS.
This change also makes use of the convention of "private" properties
being prefixed with `_`.

55e81ca4bb feat: refactor for pluggable consumers 
I've broken out the OCR-specific code from the consumers and dumped it
all into its own app, `paperless_tesseract`.  This new app should serve
as a sample of how to create one's own consumer for different file
types.

Documentation for how to do this isn't ready yet, but for the impatient:

* Create a new app
    * containing a `parsers.py` for your parser modelled after
      `paperless_tesseract.parsers.RasterisedDocumentParser`
    * containing a `signals.py` with a handler moddelled after
      `paperless_tesseract.signals.ConsumerDeclaration`
    * connect the signal handler to
      `documents.signals.document_consumer_declaration` in
      `your_app.apps`
* Install the app into Paperless by declaring
  `PAPERLESS_INSTALLED_APPS=your_app`.  Additional apps should be
  separated with commas.
* Restart the consumer
