Add conf.lua support

[Svetomech]

There are a lot of love.conf(t) function features renamed or simply missing in 0.8.0 if comparing to 0.9.0
Request some feature support for them. For renamed ones at least.
P.S. I'll see what I myself can do, of course.

Can you include some examples?

[Svetomech]

1. t.window.title = 'AppName' in 0.9.x == t.title = 'AppName' in 0.8.0
2. t.window.resizable doesn't exist in 0.8.0 yet
   ...and so on

[kyleconroy]

Hmm, I'm not entire sure how we could fix that. Do you have any ideas?

[Svetomech]

A new small library specially for that. Because changing 't' to 'glove' is not very convenient.
Or we can just create a new set of functions inside glove. And name the table something like 'g'.

you could make a file called gloveconf that returns a function which takes t and modifies it to use it in 0.9.X

function love.conf (t)
    t.screen.fullscreen = true
    t = require("gloveconf")(t) --Althought the "return t" part could be ommited
end

The code for gloveconf.lua could be something like:

return function (t)
    t.window.title = t.title or "Unnamed"
    t.window.fullscreen = t.screen.fullscreen or false
    ...
    return t --As said before this part could be ommited
end

Or it could be part of glove itself and you would need to call glove.conf

require "glove"
love.conf = function (t)
    ...
    glove.conf(t)
end
