Upload wordlists/rulesets from disk

[puzzlepeaches]

This PR adds support for uploading wordlists/rulesets from disk instead of a web browser. The functionality here is identical to the Ruby version.

Changes Made:

Directories were added to the following locations and contain .gitkeep files:

hashview/control/rules/auto_upload
hashview/control/wordlists/auto_upload

A job with APScehduler was added to hashview.py for both rulesets and wordlist that checks for new files every minute. When a new file is detected in the auto_upload folders:

1. A checksum for the file is generated and compared to existing rulesets/wordlists in the DB
2. If the wordlist/ruleset is unique, the file is imported into the database in the background

Notes:

• This PR contains the code from Adds Docker support #125. I think you should merge that first before attempting to merge this code.
• This feature has yet to be tested with very large files. Can't with my current setup.
• The one-minute interval check for new word lists might be too frequent. I cannot tell how system-intensive the file hashing is on a large wordlist. If it eats a ton of resources, the user may experience issues.
• Changes were also made to the docker-compose.yaml file to support this change for a docker-based environment. They are commented out with a note.
