Generic Object Pool

[erikwatson]

Applications build using Bramble are almost certainly going to require the use of a pooling system in order to avoid GC (Garbage Collection) stuttering when our dangling objects get cleaned up.

Object pools need the following features.

• Initialise with - Create a new pool with X of the required object
• Recycling - When we are done with an object we return it to the pool, where it's properties are reset
• Dynamic Resizing - If the limit is reached we should increase the size of the pool automatically.

It should be easy, it was easy enough in Sky Panda and it made a huge difference.
