I pushed the changes to the repository. Apart from small modifications
to existing compat theorems that made it work with current HOL Light
and adapting to current Isabelle the changes are:

I added about 100 new constant maps along with compat theorems which
means many theorems can be translated to ones talking about Isabelle
constants, in particular theorems about lists, sets (union, ...)  and
number theory (gcd, ...) are translated now.

I also tried to add maps for reals and integers; this works only
partially so I do not enable it by default in the build. Enabling
those allows translating theorems that talk about reals and integers
to Isabelle reals and integers but it fails for more complicated types
that are based on reals, mostly because I have not been able to map
'mk_real'. Without these maps all theorems are translated correctly to
copies or reals and integers.

I also needed to update 'smart_string_of_thm' as it was failing for
all theorems and I was getting the fully bracketed output.
