Remove show/hide stats, fix bugs from exploratory testing

[smartin015]

QA checks to verify correct behavior in light of #101:

• Can create empty job
• Can add items to job
• Can create second empty job and move items to the other job
• Can export gjob files from local queue
• Can import gjob files from local queue
• Can print a job with 2 repeats, containing 2 sets with 2 repeats
• Deleting gcode file displays error in queue
• Print files skipped if wrong print profile
• Await printing if wrong color
• Can drag+drop onto LAN queue and print a thing remotely (confirm with two instances of octoprint, diff profiles)
• Can edit and save a LAN job mid-print, with the correct number of items printed after edit
• Can delete a job from the lan queue
• Can reset a job in the local queue
• Can delete jobs in the local queue
• Job multiselect works
• Job multiselect-by-incomplete/completed/unstarted works
• Drag-drop job with autostart behavior works
• Can create additional LAN queue
• Can move print between LAN queues
• Can delete a LAN queue
• Timelapses saved in job history
• Job position reverted back to prev queue if LAN queue validation fails
• Completion count of sets is consistent between local and lan queues (i.e. turns back to 0 when job run completes)
• Editing and saving a lan job syncs edit state across peers
• Joining an existing lan queue also syncs files
