[REF] Use shared TabHeader.tpl for contact summary tabs as well

[ufundo]

Before

• very slightly different templates for the contact summary tabs inline in Summary.tpl and other tabsets which use TabHeader.tpl
• hard time keeping track of what keys are expected for tabs (including when using hook_civicrm_tabset ) - different tabsets need different ones
• contact tabs fallback to a puzzle piece icon, other tabsets do not
• contact tabs use a url key, other tabs use a link key
• contact tabs use an id key, other tabs use the array key from the tabs array

After

• additional parameters in TabHeader.tpl
• Contact Summary uses the shared template
• more consistency in the expected values for tabset arrays
• Manage Event tabs have icons
• all tabs without an icon will use the default "puzzle piece" fallback
• all tabs use url key in the template (this is set from the link key if not provided explicitly, for backwards compatibility)
• all tabs use the array key from the tabs array (this is set from the id key for contact tabs, for backwards compatibility)

Technical Details

Should have very minimal impact on outputted markup for now, but should be a step towards making the markup more consistent.

@colemanw my guess is no but would there be any implications on the Contact Summary Layout editor with this change?
