Update project README to reflect purpose.
Add font choice inputs and accompanying copy text.

We should try to handle the copy outside of code, but this implementation helps speed launch along.
Capture new request quantity inputs in Javascript
Justification notes aren't required, only when applicable

Adds some default text to the justification notes when not included.
Cut notes area in half, as we'll likely never need that much space.
Ensure at least one font has a quantity specified
Capture quantity for each font requested and store as meta
Code formatting
Follow sanitization pattern for asset_type
Setup initial display of captured meta data on an asset request

May be refactoring the font array in a bit, this got ugly.
Refactor how font slug, name, and quantity is handled
Use a table for tabular data! Display font quantities
Remove support for editor and author from the post type

Just because we're storing data with author and post content doesn't mean we need the default UIs for these.
Display post content in asset request details
Remove unused meta get, clean spacing

We aren't using the asset type meta data right now, so we can leave the request for it out of the meta box display.
Remove broken HTML from asset request text
Remove unused font request variable in submit processing
Save submitted email address to post meta and display when needed

We were capturing this only for the title previously, which doesn't help much.
Send a notification email to the requestor when an asset request has been received.
Prep and unprep mail filters when the plugin sends notifications

This allows us to set a mail from and a mail from name that is more expected than the default WordPress sender.
