Update progress more often (echoing https://github.com/olivierverdier/python-progressbar/pull/1)

[GoogleCodeExporter]

Hello,
if you're maxvalues is big, updates in the progress bar happen only at 
"discrete" interval, so when we reach 1%, 2%, and so on.

I noticed this issue on github: 
https://github.com/olivierverdier/python-progressbar/pull/1 (and its relative 
pull request: 
https://github.com/wonderfulll/python-progressbar/commit/a6f92b81ab6e7ea67029486
62d99ff16663d63df ) that should fix this problem, introducing an optional value 
to Start().

Please consider merging it.

Thanks,
Sandro

The current version in the repository updates at every one percent or after at 
least one second passed. Do you think a parameter like this is still necessary? 
I'd prefer if the library could detect automatically that maxvalue is too big 
and perhaps update at 0.1% intervals (although, in this case, the percentage 
would have to be printed with 1 decimal place).

Uh the new version seems very nice: time to release it? :)

I tested and indeed the updated at each second is very nice, even though I'd 
like (as a user) to be given the possibility to choose the interval of update, 
not to bother too frequently or too slowly: do you think it's a valid request?

Please please please, release the new version when you come at it :)
