Automate release notes generation

See #305 for some script drafts. Also think about better log standard (e.g. see http://keepachangelog.com/)

Revival of the self[:] syntax?

This was removed long time ago due to some undisclosed problems in numpy-sympy interoperation. See [bug](https://github.com/sympy/sympy/issues/3655) and related [page](https://github.com/sympy/sympy/wiki/Generic-interface) of the old wiki. Aside from this, now here is probably...

Probably, random.choice/sample may be used, when seed is a sequence. Everything is in CPython 3.6. Or just simplify these functions, using stdlib.

Convert prose docs to the Jupyter notebook format

See https://github.com/spatialaudio/nbsphinx for sphinx. Or something better? We also need ability to test output cells to have correct, expected output (just like we did this with doctest's).

Optimize Monomial class

Since 5436144843 there are apparent speed regressions, e.g. running time `test_solve_lin_sys_6x6_2()` was 35.23s and 62.29s - after. We should investigate if this can be improved without rewriting the stuff in...

Cleanup PolynomialRing and PolyElement interfaces

There are huge number of public methods, besides compatibility wrappers from IPolys (which also should be removed eventually). One example is that `subs()` and `eval()` methods, probably, should be same....

Make simultaneous=True - default for subs method

This seems to be more intuitive and match other CAS, e.g. Mathematica's [ReplaceAll](https://reference.wolfram.com/language/ref/ReplaceAll.html). The option should be also removed eventually.

While the modulargcd.py was extended to handle algebraic fields, the efactor() - doesn't (original paper works for algebraic fields, not just number fields). We should implement this case. Also, some...

See e.g. #157, which add the test for sympy/sympy#10268. Right now this looks: ``` In [1]: reduce_inequalities(log(x) < 300) Out[1]: 300 x < ℯ ``` Correct answer: `(0 < x)...

Lambda should be improved instead.
