Merge remote-tracking branch 'remotes/remote/master'
add rct_ride_type structure
Updated lots of ride descriptions and other things

'air time' is now 'hang tijd', we might just want to keep calling it 'air time', I'm not certain.

Changed autorondrit to rit in een karretje, which is what I remembered it as from my youth. Smalspoorweg also got changed to miniatuur spoorbaan, as most theme parks would refer to them as such.

Renamed the Heartline-twisteractbaan to Heartline-kurkentrekkerachtbaan. Twister = kurkentrekker.

Stoelrot. changed to Stoeldraaing (I'm not sure if it fits, otherwise revert to Stoelrot.)

Also changed a whole bunch of other things down the road. This is fun!
Merge pull request #362 from xzbobzx/patch-1

Updated lots of ride descriptions and other things
Created named address RCT2_ADDRESS_SCENARIO_TICKS

* 0x00F663AC is now named RCT2_ADDRESS_SCENARIO_TICKS. This variable
starts at an arbitrary value, defined by the current scenario, and
increments by 1 on every game tick.
* Also, added meaningful name to some variables in draw_light_rain and
draw_heavy_rain.
Update gfx_draw_rain declaration to match definition
