Replaced Simplex noise with Perlin noise for the 3D and 4D variants of love.math.noise, to avoid patent-infringement issues (resolves issue #997.)

Added love.math.compress(data, format [, level]) and love.math.decompress(compresseddata) / love.math.decompress(compressedstring, format).
...
Renamed the love.image CompressedData type to CompressedImageData.
love.math.compress returns a love.math CompressedData object which holds the newly compressed data. Currently supported formats are "lz4" and "zlib". Note that the formats are not file formats and don't compress filesystem hierarchies.

Updated the new module changes to use more compile/link-time checking rather than runtime checking.

Added RandomGenerator:getState and RandomGenerator:setState (resolves issue #831.)
...
getState returns an implementation-dependent string representing the current state of the RandomGenerator's PRNG. setState sets the PRNG's state to an implementation-dependent string.

Added love.math.gammaToLinear and love.math.linearToGamma for converting RGB color values from the sRGB color-space to linear and vice-versa.

Renamed love.math.g/setRandomState and rng:g/setState to love.math.g/setRandomSeed and rng:g/setSeed.
...
getRandomSeed now always returns the previously set random seed instead of the current (implementation-dependent) random state.

The Vertex struct is now recognized as POD by C++, also fixed the name to be consistent with other love structs

love.math.noise now returns values in the range of [0, 1] instead of [-1, 1]

Changed love.math.randomnormal([mean], stddev) to love.math.randomNormal(stddev, [mean]);
...
Changed love.math.randomseed(seed) to love.math.setRandomState(state) and love.math.setRandomState(low, high). Added low, high = love.math.getRandomState().
love.math.setRandomState(state) can set the random state to an integer of up to 53 bits, love.math.setRandomState(low, high) can set the random state to a 64 bit integer by using the first argument as the lower 32 bits and the second argument as the higher 32 bits.
This allows for reliable setting and saving of the state of a RNG.

Add support for Bezier curves of arbitrary degree.
...
New functions:
bezier = love.math.newBezierCurve(control-points)
degree = bezier:getDegree() -- degree = #control-points - 1
x,y = bezier:getControlPoint(pos) -- pos < 0 => string.sub semantics
bezier:setControlPoint(pos, x, y) -- pos < 0 => string.sub semantics
bezier:insertControlPoint(x,y, [pos = -1])
x,y = bezier:eval(t) -- 0 <= t <= 1
polyline = bezier:render([accuracy = 5]) -- returns a table of points
Example:
function love.load()
b = love.math.newBezierCurve(10,10, 80,400, 380,400, 470,10)
end
function love.draw()
if not curve then -- curve rendering is expensive-ish
curve = b:render()
end
love.graphics.line(curve)
end

Added love.graphics.getRendererInfo(infotype). Useful for creating more informative error reports and advanced debugging.
...
Returned string can be highly system-dependent, so don't rely on its output!
infotype can be "name", "version", "vendor", or "device"
