`==` doesn't work for `SubStaticString`

[nhz2]

julia> using StaticStrings

julia> a = SubStaticString("hello",1:2)
substatic"he"5

julia> b = SubStaticString("hello",3:4)
substatic"ll"5

julia> a == b
true

Also, is there a difference between SubStaticString{N} and just SubString{StaticString{N}}?

This is a bug. There is a difference in that SubStaticString is itself an AbstractStaticString.

Fixed in #16, 0.2.4
