Node-RED 0.20.7 released

In my case the problem was with sessionExpiryTime:

adminAuth: {... sessionExpiryTime: 3*30*24*60*60}

Probably, it's calculated in microseconds so I was getting:
3*30*24*60*60*1000 > 2147483647

The problem solved by changing sessionExpiryTime to 20 days and removing the .sessions.json

Should we really use 32-bit signed integer for this comparison?
