New: PreCache? Files so TiVo Loads Faster

This will cause pyTivo parse all files recursivly in a share to load them into the cache. Currently this only works in the video plugin, but incorporation into other plugins that use a cache is very easy.

In the video plugin this causes pyTivo to run ffmpeg on EVERY video file in that share and stores that information in the cache.

Benefits: This greatly decreases the load time while browsing on the TiVo. For me a folder with 50 videos would take 18 seconds to load the first time I viewed it. Now it takes less than 2 seconds.
Drawbacks: This will create a delay in the startup of pyTivo while processing the files. For me I experienced a delay of nearly 2 minutes to parse 757 video files.

Usage:
Set the precache=true under any share. If the plugin does not support the precache setting it is ignored.

Example:
In the following conf file the share "Old TV" would be precached while "Movies" and "Photos" would not be.

[Old TV]
type = video
path = /store/TV
precache=true

[Movies]
type = video
path = /store/Movies

[Photos]
type = photo
path = /store/Photos

[Server]
debug = true
ffmpeg = /usr/bin/ffmpeg
hack83 = true
port = 9032
