don't try to pre-load history file if it doesn't exist
give warnings when trying to connect to workspaces fails
add timestamp to log
a command that expects to receive a list of cues doesn't blow up when it doesn't get one
if QLab responds with nothing or with invalid json, don't die
rename param
add cue type-specific commands
just show status if command is not specifically handled
load the last 100 history items into the buffer in the right order :P
