Code will now perform a one time check on starting to see if the cache
has been updated to the new 2048 default. If the update has not been set
we update. After this time if the user lowers the level, it will not
reset back to 2048 by default.

When compiling with qt5, require at least version 5.0.3, fix #741

The problem was converting a negative int to an unsigned int. This was
resulting in a value of: (2^32) - n. Meaning that the room age was
extreamly old. After 48s the delay from the server will catch up and the
time diff will be 0 rather than negative, which is why after 48s the
room will change from 5+ hours to <1 min.
