Renaming the fragments.
Use support packages for Fragments.
Integrate PagerSlidingTabStrip for the tabs.

Use PagerSlidingTabStrip to display swipeable tabs, where each tab is a
fragment of its own managed by a parent fragment. Navigation drawer item
selection loads this parent fragment.
Introduce sub-package namespaces.

Rename classes and improve the package hierarchy.
Fix the crash when Connections Fragment was relaunched.

Do not store the fragments within YaniFragmentManager, instead create
new instances when required, as the fragments get destroyed on events
like screen rotation, switching to a different navigation drawer item,
etc.
Have a unified location for section titles.

- Unified location to get the section titles.
- Rename few classes to avoid confusion.
