v0.24 - Defense tab changes

v0.24 is released:

• Defense tab is now locked by default and is unlocked via the collectible at 100m.
• Defense tab is no longer unlocked in prologue
• First one-time collectible increased: +10 -> +20 wood
• Removed +10 wood collectible at 100m
• First prologue card now spawns at 50% progress instead of 0%

The defense tab change was made as defense can be a 'noob trap' that sucks up your resources early on. So it is now permanently unlocked only once on Freeplay mode, at 100m, a point you reach when you've understood the game mechanics enough I think. 

I removed it from the first time you play the prologue as well, as the storm there does not need to be defeated to win the game, thereby making the prologue less heavy.

I've moved the rewards earlier so you get more wood headstart on the first run. The first prologue card also generates faster.
