make tika CLI similar to parser.from_file

[vedal]

Thanks a lot for tika-python. its fast and awesome! 🥇

I suggest the following change to make the command line tool
$ tika-python parse all file.pdf
behave more similarly to inline python function
tika.parser.from_file("file.pdf", service='all')

Currently, the command line tool produces content in XHTML by default, while the inline function produces plain text with an option to set argument xmlContent=True (False by default), which was unexpected. It is unclear how to specify plaintext output for the command line tool otherwise.

this is an interesting suggestion thank you @vedal. In the PR, I would rather not just comment out the old code, I'd rather see a clean update. Also how do you think this will affect back compat with other users? I'm going to schedule this for tika-next (the post release milestone for discussion). Thanks.

Will close this for now. If you desire this as I mentioned, need a better patch and some doco explaining for users. Thanks for the idea though @vedal
