Wrap adjoint calls in Matrix

[ararslan]

Fixes #55.

[ararslan]

Test failures (surely unrelated) reported at #57.

[stevengj]

These should be transposes, not adjoints. Why can’t we use .'?

[ararslan]

.' is deprecated in 0.7.

[ararslan]

This will need #58 in order to pass CI.

From poking at this locally, it looks like this does not need #58 anymore (due to better deprecations in Julia, I guess). It suffers from the A_mul_B! etc. rename, though. But against an AbstractFFTs with JuliaMath/AbstractFFTs.jl#10 in, just adding

if VERSION <= v"0.7.0-DEV.3204"
    import Base.A_mul_B!
    const mul! = A_mul_B!
else
    import Compat.LinearAlgebra.mul! # Note: Need to bump Compat version in REQUIRE
end

doing s/A_mul_B!/mul!/ and fixing up the two lines in runtests.jl that invoke A_mul_B! and A_ldiv_B!, respectively, I get the tests to pass.

Bump! We now have JuliaMath/AbstractFFTs.jl#10 and can I expect to be merged this with #58?

[staticfloat]

Bump! This broke a downstream package on 0.7 (AuditoryFilters), so it'd be nice to get this sorted soon.

[ararslan]

Sorry for letting this languish for so long. Once JuliaLang/METADATA.jl#13833 is merged we should be in better shape here.

Incorporated into #64
