So I added a few methods to FastString, so it can use the writeable
interface.

I'm surprised I didn't think of this before, really...

I'm not sure who uses the writeable interface... but it's kind of
handy really. It just lets you have a class that can write a string
to... It's so simple. Could be FastString or a ElfDataFile or a
binarystream or a Shell or a socket... or user made classes or other
plugin classes from other authors.

If anyone wants an early release let me know. Or else I'll release it
when ever I feel like it :)
