RPM Spec file added for nscp
Merge branch 'feature-rpm-specfile2'
Set /etc/nsclient/nsclient.ini as default on linux

Previously nsclient would look for nsclient current directory
but on packaged linux systems it makes more sense to look in a global
location first.

There are probably similar changes that need to be done about other paths

crash locations, log files, script and module paths come to mind.
Merge branch 'fix-config-paths'
travis.yml - only use gcc to compile

Previously we were also building with clang, but build does not
work with clang (yet).

Sticking to only gcc for now.
