* Fixed a regression in 'web/rdcastmanager/Makefile.am' that caused
the incorrect executable to be installed for 'rdcastmanager.cgi'.
* Refactored SQL statements in 'lib/rdweb.cpp'.
* Modified 'conf/Makefile.am' to install 'rd-bin.conf' in
$(sysconfdir).
* Updated 'INSTALL' to include information about the '--sysconfdir'
flag.
* Updated 'get_distro.sh' to detect RHEL 7 correctly.
* Modified the installation script to work on RHEL 7 in
'rivendell.spec.in'.
