This revamps the type configs for swaynag. All sizing attributes for
swaynag are now `ssize_t` instead of `uint32_t` to allow for a default
value of `-1`, which allows for `0` to be a valid value. Additionally,
the initialization of the type configs has been changed from a simple
calloc to use a new function `swaynag_type_new`. `swaynag_type_new`
calloc's the memory, checks for an allocation failure, sets the name,
and all sizes to -1. The layering order has also been changed to
default, general config, type config, and as highest priority command
line arguments. Finally, `swaynag_type_merge` has been modified to
handle the layering and sizing changes.
Fixes segfauls for any case where swaynag->outputs was not inititalized
including -h/--help, -v/--version, and invalid arguments.
Sets sane defaults for colors not given. Any color not given will
fallback to the default color values for type error.
Adds support for a hidpi cursor
