The overloaded log() is a unary operator, so don't pass additional
arguments.

Fix blog() so the cases $x->blog() and $x->blog(undef) work correctly. An
undefined base means that blog() should use base e (Euler's number).

Both CORE::log() and other mathematical software returns inf for log(inf),
so we do the same.

Add tests for log() as well as templates for future tests of the other
overloadable functions.

Improve descriptions of a few tests.
