fixed some output issues in generateWallpaper.py

[zaphbbrox]

Fixes #9 :

• Using top -b -n 1 -i in updateWallpaper.sh to get states of currently inactive programs.
• Using -1 in generateWallpaper.py to get the last part of the split command (which should always be the name of the program, right?)

I just tested if this still works if this still works when Zero_suppress=1 is in /etc/topdefaultrc. It doesn't. So for this problem there's still a fix needed.

I tested out your code on my machine. Unfortunately, it doesn't work here. On my system, the output of top looks like:

top - 19:51:58 up 12:01,  1 user,  load average: 0.40, 0.60, 0.60

So using the last part of the split command doesn't work like it does for the absolute paths your getting in your output.

OK, I wasn't aware that the output of top differs so much. Also I noticed I still used the -u(ser) switch for the top command. Without it I had entries like:

    2 root      20   0       0      0      0 S   0.0   0.0   0:00.00 [kthreadd]

which I have strip and split differently. I don't know if it's because I'm using Manjaro KDE edition or something else.

So I close this pull request for now.
