Create SLua scripts by default

[bennettgoble]

Description

When a script is created with the Lua Editor Project Viewer it should be a SLua script instead of a LSL script.

Acceptance Criteria

• Selecting "Create New > New Script" in inventory creates a SLua script
• Clicking "New Script" from object inventory should create a SLua script
• SLua script has the same behavior as the default LSL "Hello, Avatar!" script

Most residents on Second Life are more familiar with LSL than they are with Lua. Doing this will be both confusing and cumbersome, especially since Lua hasn't even came out of alpha yet, and the decision to make it the new default before a good majority of scripter residents expect LSL as the default.
I propose that the default be moved to LSL / Luau (as opposed to mono), with the option for people wanting to use SLua as their default as a option in the Preferences.

@FelixWolf thanks for the feedback, the intention here is to make working with SLua as easy as possible for the duration of the Alpha and Beta. Likely the default for the mainline viewer will continue to be LSL.

@bennettgoble In that case, this is a completely reasonable request! Sorry for the mis-understanding, apparently others got confused about it in #scripting-lua as well, so I figured I'd put it here instead of let it get lost in discussion. I've informed everyone there of the intentions.
Thanks!

This should be done on the server side.
The viewer-side solution is a temporary workaround that should be reverted once the server-side fix is implemented.
