Grammar police

Fixed a couple of minor typos in the readme.
Backported conf/MC_VERSION from 1.6.2 branch.
Version bump to 1.0.1.
ServerProxy doesn't exist.  That was a dumb bug.
The server doesn't like ItemStacks without a valid item.
player.getPosition is client-only
Added versionBounds, bump to 1.0.2.
Moved the render hook to a better location.
Updated rendering method to match new hook location.
Version bump to 1.0.3.
Made it possible to see everyone's held blocks.
Fixed a pointless NPE from trying to sync too quickly.
Switched to a private Tessellator.

This should avoid conflicts with anyone else who's tessellating at the point
we insert our hook.
Use our private Tessellator for RenderBlocks.
Fixed your blocks appearing far too high.

Other players may still show theirs too high; I'm not sure if their positions
are already offset as well.
Upgraded coremod to use new mcp_interface replacement.
Tweaked the render hooks AGAIN.
HookFinder now works properly when recursed.

Previously, processing a class while already in the middle of processing one
would cause the outer class to stop processing properly, leading to hooks
not getting inserted.
Stopped blocks from flickering/changing as you try to pick them up.
Version bump to 1.0.4.
