Anrxcs Widget Set

• This is a small collection of custom functions to be used with wicked.

• All the beautiful.*.widget references can be replaced with custom colors (i.e. "#ffffff" for white), or include them in your theme file.

• Where data parsing is required only awk is used, so there are no "cat+head+tail+sed+awk" combinations
