* Add uri identifiers to all data source things and make them the same
1. Add uri identitifer to data-source service
2. Make <EventSource /> and <DataSource /> as close as possible
3. Add extra `.closed` method to get a list of inactive/closed/closing
data-sources from elsewhere
* Make the connections cleanup the least worst connection when required
* Pass the uri/request id through all the things
* Better user erroring
* Make event sources close on error
* Allow <DataLoader /> data slot to be configurable
* Allow the <DataWriter /> removed state to be configurable
* Don't error if meta is undefined
* Stitch together all the repositories into the data-source/sink
* Use data.source over repositories
* Add missing <EventSource /> components
* Fix up the views/templates
* Disable all the old route based blocking query things
* We still need the repo for the mixin for the moment
* Don't default to default, default != ''
* ui: Split up client/http and replace $.ajax
This splits the client/http service more in the following ways:
1. Connections are now split out into its own service
2. The transport is now split out into its own service that returns a
listener based http transport
3. Various string parsing/stringifying functions are now split out into
utils
* Remove jQuery from our production build
* Move the coverage serving to the server.js file
* Self review amends
* Add X-Requested-With header
* Move some files around, externalize some functions
* Move connection tracking to use native Set
* Ensure HTTP parsing doesn't encode headers
In the future this will change to deal with all HTTP parsing in one
place, hence the commented out METHOD_PARSING etc
* Start to fix up integration tests to use requestParams
