This adds the ability to specify cursor attributes as part of their
file names, which allows us to remove hard coded values like the hot
spot from the code. The attributes can be specified between the last
two dots of the file name. Each attribute begins with a character,
followed by one or more digits that specify a uint value.
Supported attributes:
x: The x-coordinate of the cursor hotspot
y: The y-coordinate of the cursor hotspot
f: The number of animated frames horizontally in the image
t: The number of milliseconds per frame
For example, the filename wait.f14t100.png specifies that the image
contains 14 frames that should be cycled through at a rate of 100ms.
The hotspot is not specified, so it defaults to the center.
It didn't feel right to have a "DHCPClient" in a "Servers" directory.
Rename this to Services to better reflect the type of programs we'll
be putting in there.
