Fix rain state for <= 1.6.4

In 1.7 rain handling was moved serverside. So rain strength is now sent
from server, and rain appears when strength is over 0.2. Server still
sends start/stop rain game event, however the raining flag no longer
does anything clientside. Yet the same start/stop rain game event also
sets rain strength, and to make it worse, start rain sets strength to 0
(which also kinda stops rain for a tick) and stop rain sets strength to
1, so they work in reverse since 1.7 (WTF mojang?).
Versions below 1.7 only support starting/stopping rain, not setting it's
strength so translation is done as follows: rain strength > 0.2 as start
rain, < 0.2 as stop rain, start rain game event as stop rain, stop rain
game event as start rain. Since start/stop rain game event on old
versions will reset rain progress, start/stop event is only sent when
weather changes, not on any game event.
