Make some admin
Show full admin url on secret admin page
Show page name in secret admin title
Get page_name from form if available

We were just getting it from the subdomain, which was a bit foolish for
new pages and actively broken for the form on page-already-exists.

Fixes #1
Remove hyphen from homepage title
Merge branch 'master' into feature/adminpages
Use processed data from form instead of raw
Validate page_name for r'^\w+$' as well as length
Render page_name field properly
Redirect to secret admin after page creation

Fixes #13
Generate secret from wordlists
Neaten up the wordlists
Use uuid for secrets
