Separate out feed fetching functionality so that it can be re-used.
Integrate the Transport "mode" into the Transport "type" dropdown. It's unlikely that you'd have a client that's both push and pull and other.
XML Client: implement test_connection method, see #15
Move inline CSS into separate file.
Use checked() helper function, see #17
Remove unnecessary serialize call; add_post_meta will take care of that.
Another unnecessary serialize call before add_post_meta
XML Client: Clean up some up the styling on the Edit Site page, see #22
Fix overlapping styles for xpath rows
Fix usage of checked() functions; the value stored is either 'true' or 'false' and we need to check against those.
Pull: Don't store inserted IDs/GUIDs in a a big meta array.

Store them individually against each post so that we don't have to worry about scalability issues when we have 1000s of posts pulled.

fixes #9
Settings Validation: don't allow cron to less than 5 minutes.
Sanitize selected_sitegroups before saving.
Stop saving syn_transport_mode; it's useless.

Show the client type on the "Sites" list screen.

fixes #14
XML Client: custom nodes should be under a separate key in the node_config to avoid confusion with other keys.
Pull XML: Remove get_guid method.

It's not really necessary since the XML has the GUID and our save process will determine whether the post is new or not. It was also changing the GUID to the ID every time, which was probably breaking stuff.
fix typo
