Bugfix release.  Still not completed version.  Options -x and -l added.

Demangling of names added.  You must tell the cachedir if
demangling filenames from the filesystem, else use option -e.

Example:
<pre>find out -type f -print | filecache -dxf out</pre>

Demangling runs until the end of the name or the sequence '$.'.
Latter is for extensions, as you perhaps like to store all JPG style
files as someting.jpg or have several "backups" of a file, like done
with `mvatom -b`.
