mem: allow standard float formatting syntax

Floats in mem.py can now be formatted with a standard format string
(e.g. {avail_mem:.2f}) instead of needing an extra `round` parameter.

This brings this module in line with the expected behavior in the rest
of i3pystatus.

Optionally skip MAC address check in network

Network interfaces don't necessarily have a MAC address. For example,
the tunnel devices created by OpenVPN do not. Previously, passing a
network interface that did not have a MAC address caused the network
module to fail, since it assumed that there would be one.

This commit just adds a flag to the network module "mac", which defaults
to True. If True, the module behaves like before. If False, the check
for the MAC address is skipped and the {mac} format variable is replaced
with "NONE".

I tested this with my OpenVPN interface as well as my regular interface
and it works fine.
Better checking of the MAC address

Use a Try... Except... block instead of a function flag when checking
for the MAC address. This has the benefit of requiring no changes for
user, but fixes the problem with interfaces that do not have MACs.
