Working directories are now set seperately from the commands so they
can later be swapped out when running linters over projects is
supported, and also better support filename mapping for running linters
on other machines in future.
* fix cppcheck for 1.89+, and add column support
In cppcheck 1.89 the output changed to be more like GCC. This commit
forces any version of cppcheck to output in that same format. This also
allows for ALE to pick up the linter's column information
* Add parameters to tests. Vader passes.
* Fix c cppcheck for v1.89
cppcheck is now run without the --project option and from the buffer's
directory instead when the buffer has been modified. Saving the buffer
will get results by linting the project instead.
