add triple-quote string literals, e.g., """abc"""
add asum to BLAS
add faster specialized implementation of norm(x, p) for vectors
add asum method for Array
fix minor spacing issue (use spaces instead of tab)
strip leading whitespace from triple-quoted strings (closes #70)

For example,

    s = """
        a
         b
        """

is now equivalent to "a\n b".

improve float ranges, for #2333

another float range fix (#2333). thanks to @stevengj
switch math.jl fallbacks from ::Real to ::Integer so you get no-method errors for undefined functions on new floating-point types, instead of infinite recursion
fix compile-atlas target
add elliptic integral functions, elliptic[efk] (closes #2337)

Not totally happy with the names, especially `elliptice`.
`ellipticE` would be a bit better, but breaks convention.
Update doc/manual/types.rst

Fix some typos and clarify some wording.
