Add support for dynamic linking

[FinnWilkinson]

Currently only statically linked binaries are supported which can have some limitations on binaries which can be run. With the introduction of a virtual memory system in the multi-thread-support branch, dynamic linking should now be possible.

This will also allow for other binary file types (such as Mach-O) to be supported, and should help with cross platform compilation & execution (as discussed in issue #180).
