[TYPO3-50-general] Common namings for variables with path-content

Hi @all!

If you have a variable-name, sometimes it is unclear what the variable 
realy contains, because of double meanings.

There several names for a "path" aka "folder" aka "directory"

directory:
An absolute path, which must exists. (PHP: is_dir() === TRUE)
e.g. is_dir($someDirectory)

path:
Might be a relative path or a path which might not yet exist.
You have to "manipulate" the variable-content to achieve a 
directory/absolute path (PHP: is_dir() === TRUE).
e.g.
is_dir($someDirectory . $somePath)
is_dir(realpath($someRelativePath))

folder:
Normally just used in the windows95-world. Shouldn't be used.

It would be nice if you always know what kind of path it is, without 
looking at the API or the code.

Cheers,

Malte
