#29 New cpu, memory and net load plugins

[init_sub]

This patch adds two new plugins to fbpanel - memory and
network load and modifies two another: cpu.c - now it
shows digits, not graph, dclock.c - make font regular
(was bold) and fixes transparency problem.

New config properties:

type = net
config {
Action = program # action on click
Interface = eth0 # network interface to count
Minimum = 0 # minimum value to show
Width = 0 # fixed width in pixels (variable
width if zero)
Interval = 1000 # interval in ms
}

type = cpu, mem
config {
Action = program # action on click
Width = 0 # fixed width in pixels (variable
width if zero)
Interval = 1000 # interval in ms
}
