Fix promotion rules

v0.5.3

avoid infinite loop in promote_rule (#113)

1.0 Compatibility

v0.5.2

Remove a couple extra deprecated identifiers

v0.5.1

showcompact(io, ...) -> show(IOContext(io, :compact=>true), ...) (#110)

First 0.7-only release

Includes only cleanups for 0.7 and drops deprecations from prior versions.

Fix typemax and friends for overflow

avoids integer overflow on left shift (#106)

in several places the conversion machinery uses `1<<f`, which is a
problem for `Fixed{Int64, 63}`, and `Fixed{Int32, 31}` on 32-bit machines.

This changes those to `one(widen1(T))<<f`.

Fixes #104.
