moved menu share icon to advanced save dropdown, optimized loding of share modal
more modal loading optimizations
A lot more work on annotations (#44, #8). Graphite events is working, editing, icon size, color and vertical line toggle/options working. To sleepy now...
First attempt at influxdb support.

What works:
- declare influxdb datasource in config.js
- can add simple metrics or write arbitrary select statements
 - time and group_by reflect current view
- graphs seem to be draw correctly
- flat schema metric picker

What doesn't work:
- breadcrumb navigation in target composer
- hierarchical schema in target composer
- target functions
Add some annotation support.

Enter a query in the 'tags' box. The first non-time, non-sequence column is
used as the 'data' parameter. Could maybe return all column/values
as tags or something.
