0.4.0-alpha

Changes:

• #39 - Support for internal links. Internal links to other wiki pages are now supported (i.e., will no longer refresh the page) if the links are in the form /wikis// note these are ids (uuids), not slugs. A new editor is planned to make inserting these internal links easier. You should probably just ignore this feature until then :)
• #20 - Basic search for users in the admin user management menu is now supported. There is a new script in scripts/db_update that must be run to enable this.
• Updated the markdown parser to Commonmark 0.23.0 (go-commonmark and commonmark.js)
• Much refactoring and bug fixing.

Note: The index.html file was previously buried in the frontend/web_app directory structure. This was inconvenient as this file would need to be edited if you wanted to apply some customizations (logo, meta tags, etc.). This has been moved up to the frontend/ folder, in the form of an index.html.template file. This will need to be copied to index.html (in the same directory), then you can make edits to index.html. The config.py script performs this copy operation for you if you are doing a fresh install.
