[Python-3000] Mini Path object

Scratch the bit about normalisation not being defined on the path algebra 
object - as the latter part of the previous email noted, normalisation *is* 
path algebra based. It just has the problem that whether or not the normalised 
version means the same as the original on a given filesystem depends on 
whether or not the original involves backtracking after following a symlink.

It's abspath() and cwd() that don't belong on the abstract Path object - the 
former would be a zero argument instance method of FSPath objects, while the 
latter would be a class method of FSPath. In both cases, the result would be 
an FSPath since it relates specifically to the current filesystem (and is 
OS-dependent, as an absolute path on Windows starts with a drive specifier or 
UNC name, while one on a *nix system will start at the root directory).

Cheers,
Nick.
