Updated inbuilt commands description

Did this to meet help format standards.
Added README

Credits from startup sequence.
Merge pull request #38 from tigerw/master

Added README
Rm'd startup credits & mv'd to README

Removed as I feel it serves no purpose other than spam console and bury real error messages from plugins, etc. This is especially the case with running under screen, which makes it very difficult to scroll up or down.
Commented out groups spam

Further reduces chance of error message burying.
Revert "Rm'd startup credits & mv'd to README"

This reverts commit 2383977fe76287f4a3cc93c802d83966726ee8a4.
Removed some stuff again.
Removed all example ini files from Install.

They are copied from MCServer by the nightbuild script.
Merge branch 'master' into BlockTracing
First attempt at implementing a cLineBlockTracer class

Not yet tested, will probably have lots of bugs, if it is at all usable.
Ignoring all .ini files in the MCServer folder.

Only the .example.ini files are supposed to be in the repository and they must be added specifically by name (git add -f <filename>). All the other .ini files are considered instance-specific and are not to be put into the repo.
cItem: Removed a warning emitted when creating an item from air
LineBlockTracer: Fixed initial errors
cWorld: Added a self-test for LineBlockTracer, disabled by an #ifdef.
