maximize: Stop mixing horizontal, vertical and both.

Before this commit, do this:

    c.maximize_hoizontal = true
    c.maximize = true
    c.maximize = false
    assert(c.maximize_hoizontal)

Would not work because the states were not preserved individually.
This commit fixes that. Awesome wont be confused about it's own
state anymore.

This may seem pointless, but when it come to undoing these
maximizations, it was ambiguous.
