#49 nice priority value error

[hoosns]

With unixtop (3.8beta1) in interactive mode, if a space character is put before a
nice value, the typed value is ignored and a value of 0 is used instead.
For example:

renice 9 12345

...works ok, but:

renice <sp>9 12345

...results in the process 12345 having a nice value of 0, instead of 9.

The attached diff passes over space characters and is a possible fix to the problem.
(diff also at http://cyodesigns.com/unixtop/commands.c-3.8beta1.diff\)

The renice_procs() function will now behave like the kill_procs()
function. Where you can probably guess the code was copied from ;)

I have only tested this on 3.8beta1 on OpenBSD.
