Fix the restart command sometimes deadlocking the server
Prevent Unbounded IntCache Growth

Based on work by Peter Lawrey, this commit prevents unbounded growth of the integer cache and instead caps it to a value specified in the configuration (1024 by default). Should prevent thrashing, especially around world generation.
Shave nearly 2mb off jar size by not embedding our copy of trove since Minecraft now includes it.

Add a new subproject MinecraftRelocate which will generate a minecraft-server jar, but with the net.minecraft.util libraries in their original package.
Update Guava to 11.0.2.

Whilst it is possible for a change such as this to be breaking, the version bump in itself is very small and Guava only removes APIs after 18 months deprecation. Given the proliferation of servers such as MCPC bundling Guava versions of 14.0 upwards as well as the fact that developers should steer clear away from using deprecated APIs, it is very unlikely this change will cause any issues. Furthermore this version brings multiple bug fixes and represents the minimum version required by Minecraft itself.
Fix Jenkins build - don't try and deploy unless forced to.
