libsaria: Don't save on preference initialization
...
When a preference is initially created, it should be set to a default
value. If it is set to a default value, then we don't need to save it
immediately. Let's wait until it changes before actually doing a
save...

libsaria: Don't immediately enable preference saving
...
We shouldn't need to save preferences during startup because at this
point only the initial values have been set. If nothing is changed,
then nothing needs to be saved and we can save some time. This should
also prevent any problems caused by crashing during a save.

Val trees walk values
...
Val trees can walk through their values in addition to their paths. A
doubly-linked val tree can also walk values backwards.

and doubly-linked flavors.

Doubly linked filesystem trees are both a doubly linked tree and a
filesystem tree. They can walk paths backwards.

Rather than computing the child id for every iteration of walking
backwards, we do it once.

Add DLTree()
...
This patch adds a double-linked tree class for use in storing the
library. This class can walk backwards from a leaf node when
walk_backwards is called.

FSTree()
...
FSTree() is a tree representing paths in a filesystem. It has functions
for inserting paths and returning the paths it is storing. A path is a
UNIX path: "/home/bjschuma" is the path to my home directory.
