Remove dependency on yodl tools and remove ccache-swig man page

Use the CCache.html docs instead of the ccache-swig man page.
The yodl2man and yodl2html tools are no longer used and so SWIG no
longer has a dependency on these packages which were required when
building from git.

Closes #286
Closes #128
