Fix inclusion in translation units with exceptions disabled. (#196)

If exceptions are disabled via `-fno-exceptions` or `INJA_NOEXCEPTION`, the use
of try-catch is disallowed by the compiler.

This patch makes does two things:
* Gates the use of try-catch in one translation unit on the definition of
  `INJA_NOEXCEPTION`.
* Make it such that translation units compiled with `-fno-exceptions` but no
  `INJA_NOEXCEPTION` implicitly sets `INJA_NOEXCEPTION`.

In the specific case of `ifstream::open`, setting the exceptions bits without
exceptions enabled should trip an assertion just like INJA_ABORT. The nice
message will not be present however, but that is absent when using INJA_ABORT as
well.

After this patch, inja can be successfully included without issue.
