v1.3.5: Fixes global gfxmode in server

In re-implementing the image server I had made the current graphics mode state global. This would be a problem if there were multiple clients for one server since images would be generated for whoever last set the graphics mode.

v1.3.4: Disables BASIC on systems where this can be an issue.

See the merge comment...

v1,3,3: Server command line additions

Added:

--port Control the port that the server binds to listen on
--loglevel DEBUG,INFO,WARN,ERROR,CRITICAL Output level of the logging system

v1.3.2.1: Permissions on yeet_to_yail change to make it executable

Full Changelog: v1.3.2...v1.3.2.1

v1.3.2

Fixes to the yeet_to_yail service that adds a command line option for specifying the camera device name.

Full Changelog: v1.3.2...v1.3.2

v1.3.1: Stream files or directories specified on the command line

Added an ability to the yeet_to_yail server to specify, on the command line, directories or a list of files to stream.

To select this from the YAIL client, you enter "stream" with no arguments and the server will stream the found image files.

Added tool directory with a py script for converting either a set of directories or a list of files to YAI files.

v1.3.0: YAIL... now with vid's!

v1.3.0 Release includes a new server, yeet_to_yail.py, and new client capabilities that render video from an webcam attached to the server machine.
It will render in the current graphics modes (8,9)
There is a new client console command video that is used to kick off the video streaming.

v1.2.20.1: Internalize the welcome splash, welcome_splash.h

No longer streaming from the yailsrv. Initializing the memory used as the "framebuffer" with the welcome splash image. No longer need to clear on startup.

In the original commit I forgot to include the welcom_splash.h file. This fixes it.

Full Changelog: v1.3.4...v1.2.20.1

v1.2.19: Welcome splash screen

The current implementation just streams it from the yailsrv.
Not an optimal solution, but it's something.

Full Changelog: v1.3.4...v1.2.19

v1.2.18: Attract mode redo two

Changed the attract mode control to, while streaming, the original code that disables it repeatedly while streaming. Then enables a VBI that pounds the setting when done streaming.

Found a bug with the app key saving... it wasn't saving due to an improper handling of return value when opening the key. Ooops.

Changed some diagnostics in yailsrv with respect to counting the number of clients.
