Wiki 1.4 Install guides still reference Felix dir

Steps to reproduce:

1) https://opencast.jira.com/wiki/display/mh14/Install+Source+OS+X

• References Felix dir in the plist, Should be the 1.4.0 directory

2) https://opencast.jira.com/wiki/display/mh14/Install+Source+Linux

• Is linking to a felix dir needed?
  "ln -s /opt/matterhorn/1.4.0 /opt/matterhorn/felix"

3) https://opencast.jira.com/wiki/display/mh14/Upgrading+Matterhorn+to+1.4

• Is the following a correct to deploy to a felix dir?
  "So if you were rebuilding a capture agent, and had used the defaults when installing the system, you would execute the following from inside the 1.4.0 code checkout
  mvn clean install -DdeployTo=/opt/matterhorn/felix -P capture,serviceregistry-stub "
