fix duplicate ssh keys in keys, now shows the hosts that use that key if u tap on it

added theme deletion
added animations on change of themes list
getkeys doesnt return duplicates, thanks to:
wrote a custom == operator to check if keys are the same, ignoring uuid
added gethostskeysusedon to get the hosts that use a key
fix refreshing of hosts on modification
added cancel to import alert
