brz 0.8.2 - Disable progress bar and enable it only on -v option

[Jari Aalto+usenet]

Hi,

I'd like to propose that the new progress bar added would be disabled
by default. 

1. Through remote modem connection the extra characters displayed in
   rapid succession for many files drains up the bandwidth.

2. In local machine the screen flickers constantly on adds.
   The operations are so fast, so the value of progress bar
   go unnoticed (the flickering is a bit disturbing).

It's good that most of the commands do not return no output at
all in default state, which is good for slow connections.
