adding a worker info page
workers actions - enable disable

- removed the (enable/disable) buttons in each client row
- now you need to check a worker and enable an action.
- selecting mutliple workers and apply a batch action doesnt work
yet...
 + need to add refresh dataTable to show new status
fix : make worker status lowercase

so that we get the correct color from CSS class.
problem : "enabled" doesnt seem to be a valid class, its jquery
keyword...
Merge pull request #18 from cyprusglobe/master

Small Changes for job dispatching and shot completion
Added more worker information like mem usage, cpu usage, load average

Added caching for run_often reason for it so you can spam the refresh button (more earlier on resources this way)

New Dependencies (psutil, gocept.cache)

Changed Readme.md to reflect new dependencies
