Split up conky.config.

[simotek]

Config is now split into 3 parts and merged dynamically:

• core config - this should always be the same for polycore
• wm config - window manager specific issues
• script config - config specific to this instance / theme

The script config is able to overwrite any of the other options if desired.

The reason for this is two fold. 1 i'm sick of dealing with some of the differences here, 2 as themes move more toward being lua only like some of the examples i'd like to reduce the amount of unneeded code in the main configuration file.
