Minor bugfixes for FreeBSD 10.0-RELEASE

Fixed 2 bugs:
- Uptime Widget crashed on load due to the fact that Libc is probably missing or no longer GCC but CLANG in FreeBSD 10
- Fixed Samba Config location (FreeBSD uses /usr/local/ for user services/applications, hence smb.conf is located in /usr/local/etc/smb.conf)
