adminifier: theme editing

[cooper]

It would be nice to be able to manage themes from a server admin account.

desired capabilities

• browsing the available themes
• creating themes based on read-only embedded ones
• duplicating themes
• editing the .tpl files on the fly (except for read-only ones)
• uploading static/resource files (stretch goal)

Currently, server.dir.template can be a comma-separated list of paths to search. Wikis can also specify an absolute path with template in wiki.conf. Point being, they can exist anywhere.

I think we should make a server.dir.theme which stores editable themes managed by the server. Only those within this directory would be editable. Others would be visible but marked external. The default location would be ~/quiki/themes.

If the theme is within the wiki directory (indicating it is specific to that site), non-server admin users could edit it too maybe, within the context of the site. I don't know if this is feasible right away. If it is, it should also be possible to copy any known theme to within a wiki.
