Improve url hash treating

[OleksiyRudenko]

Url hash is used for:

• navigate within a page
• switch between sub-components render (embedded elements)

Issues:

• on page load intra-page navigation doesn't work (try navigating to #more-data or #main-data clicking on relevant link)
• when sub-component switched url doesn't get updated
• switching sub-components form side nav menu doesn't work

Suggested approach:

• sub-component switch should work by changing url hash
• url hash change should be intercepted
