Merge pull request #150 from amnonh/no_tab_select

OSv GUI: Updating the tab routing
OSV-GUI: Add slash to dynamic tabs

Dynamic tabs are hidden in default and shown only when the relevant application
exists (i.e. cassandra, jvm etc') they are searched by their path. They need to
have their path terminate with a slash to be inline with the other part of the
GUI.
