* Clicks update alerts filter text
- Normal click replaces filter with selected label
- Modifier (ctrl, cmd) + click appends to filter
* Auto-filter when clicking labels
* ctrl+click removes already present matcher
* Match arbitrary whitespace before/after comma
* Run elm make with --yes
* Always add labels to the filter
* Updating filter currently sends Noop msg
For now we are still going to require the user to
explicitly click "filter" before we send an API
request to update the list.
* Including glue between Alertmanager server and Elm UI.
* Rebuilding assets (ui/bindata.go).
