Implement case-insensitive instant search by process name

I would consider the issue as a "cosmetic bug".
Steps:
0. Run Tasque application
1. Open gnome-system-monitor
2. Switch to Processes tab
3. Do an instant search via typing letter keys: "tasq"...

What is expected:
It should be able to find Tasque as well as any other process with capital letter(s) in the name.

What is faced:
Cannot find the Tasque process as its name starts from the capital "T" and the search is case-sensitive.

The reason why it makes sense to fix:
The user does not have to know the proper case of process name.
On the other hand, the processes list sorting by name is case-insensitive - and it's well.

Thanks!
