COMPLETELY rework filename extension detection. Now the only requirem…

…ents are:

1 - executable phars must contain '.phar' in the filename
2 - non-executable phars must not contain '.phar' and must have an extension of at least 1 character

In addition, phar filenames must exist if opened for read, and the directory containing the phar must exist if opened for creation
if opened for creation, the file must not already exist
