Tyler Palsulich updated NUTCH-1912:
-----------------------------------
    Attachment: NUTCH-1912.palsulich.1-13-15.patch

Patch with the following fixes:

* If the arg mimetypes is not given, accept/dump all types.
* If the segment dir argument is invalid, print an error message.
* Remove two unused variables.
* Improve the description of the mimetype arg.
* If there is an exception, print the stack trace to console.

These are all very small changes. I'm happy to split them into multiple 
issues/patches, if desired.

> Dump tool -mimetype parameter needs to be optional to prevent NPE

> There is a bug in NUTCH-1869 which, although the new feature works correctly, 
> can result in a NPE if the new flag is not provided. This is hellish.
> We can possibly add an 'all' option which would dump everything.
> The purpose of NUTCH-1869 was so that you can have fine grained control over 
> what content you wish to dump.
