Improve Taylor1{TaylorN{T}} mixtures (#333)

* Add tests for  Taylor1{TaylorN{T}}

* Add fixorder to Taylor1{TaylorN{T}}

* Add methods for arithm opers for Taylor1{TaylorN{T}}

* Add methods of ^, sqrt, pow!, sqr!, sqrt! for Taylor1{TaylorN{T}

* Add specialized methods for most mutating functions

for Taylor1{TaylorN{T}}

* Implement suggestions by @PerezHz

* Fix error in docs

* Use TS

* Improvements for evaluate

* Clean up commented (old) code

* Remove some superfluous methods in evaluate

* More fixes

* Fixes and clean-up of `evaluate` methods

* Returning a zero Homogeneouspolynomial is of order 0

* Scattered fixes and clean up

* Fix documentation

* Remove evaluate methods for TaylorN with Varargs,
and fix tests

* Fix _evaluate for mixtures, and new tests

* Methods of evaluate for Taylor1 involving TaylorN
(fixing certain type instability)

* Add tests for new evaluate methods

* Bump minor version

* Remove a `@show` left there
