Vacancy dashboard page

Create a CRM_Core_Page class for this.
Use BAO functions to fetch necessary data and assign it to tpl
Tpl should be broken into smaller chunks. Main tpl should be layout only.
Use sub-tpls for recent-activity view and summary views.
For summary view, stages can be marked up as <ol> with a <li> for each item (containing link - don't forget the "title" attribute - see mockup)
