1. New -n and -n@ switches set additional include
filters, so only files matching the mask will be processed.

2. New -id[c,d,p,q] switch. Additionally to previously available
-idp switch (disable percentage indicator), switches -idc, -idd
and -idq instruct the console RAR to hide the copyright message,
"Done" message and all information messages.

3. Switch -e+ allows to specify file include attributes mask.
For example, you can use -e+h switch to compress only hidden files.

4. Switch -ver[n] supports the optional 'n' parameter also when
archiving. It limits the maximum number of file versions.
