Extend to install 11g or 12c

Tested with weblogic 11g installation for wls1035_generic.jar (WLS 10.3.5) silent installations on CentOS 6.4 / 6.5.

Also extended to allow more customization via weblogic.install_java and weblogic.install_init_d booleans.  All defaults in the cookbook are respected for how it was in 12c.

Note:  The server_spec of the test cases are unrunnable in current chefDK / serverspec 2.0 - and could use updating.
