Correct besseli(nu, 0) & besselix(nu, 0) with nu<0 and nu an Int. (#34)

* Correct besseli(nu, 0) & besselix(nu, 0) with nu<0 and nu an Int.

An AmosException is thrown for besseli(nu, 0) or besselix(nu, 0)
due to the call to _besselk.
However, for integer nu, besseli(nu, 0) = besseli(-nu,0) = 0 and
similar for besselix.  A test is added before calling besselk.

* Correct test for AmosException in besselix(nu, z)

besselix(nu, z) is divergent for z=0 and negative nu, only if nu is
not an integer.

* Correct besselj and besseljx for nu<0 and nu an Int.

* besselj(nu, 0) and besseljx(nu, 0) should equal 0 for integer nu!=0.
  AmosException was thrown for z=complex(0).
* Tests corrected and more added to runtest.jl
* Changed `if sinpi(nu) == 0` to `if isinteger(nu)`

* Additions to runtests, parens in sincosint, hope to increase coverage

* Attempt to get coverage test past at-horner macro.
