SilentSpike 0cd904bdc3 Add public function documentation script (#5253)
* Remove obsolete event rename script

* Add initial function documenting python script

- Currently only finds all public/invalid function files
- Method "document_public" is in place to handle the data taken from a
  function header, but currently unimplemented

* Add author/description/arguments processing

* Improve console logging and add return processing

* Use class based approach for better data handling

* Add argument processing with support for notes

* Implement rudimentary doc output

* Add return and example processing

* Fix example variable

* Fix documenting no arguments/return

* Fix malformed return handling

* Improve control flow

"""
Author: SilentSpike
Crawl function headers to produce appropriate documentation of public functions.
Supported header sections:
- Author(s) (with description below)
- Arguments
- Return Value
- Example(s)
- Public (by default function will only be documented if set to "Yes")
EXAMPLES
document_functions common --debug
Crawl only functions in addons/common and only reports debug messages.
