Close on HOME and Clarify Manifest.

The manifest now explicitly states what the Settings Activity parent is
for older API versions. Making it work properly.

The Activity now just closes when it loses focus. Including the home
button.

This is the basic idea for #53 but still needs to have considerations
for opening things like the camera app.
Added basic first content of the README about the app.
Added instructions for when unclear
Switch to sentence per line structure
Expand Project Description.

Discuss the sharing aspects of the app. Both of the files and what we
want to do in regards to offline sharing.
Expand near-future goals

Expand on the hiding goals; separate those from the other goals.
Expand on the other goals for data sharing.

Minor addition to the project description.
Create caveats section.

Explain why we have caveats.

Add the list of potential things that can cause serious trouble.
Which is mostly dataloss.
Fix conflicts and make the closing selective

The application now does not close if the camera of file picker requests
are made.
For the other situations it just closes the app.
Apply codestyle and javadoc changes.

Apply the codestyle to ContentFragment and HomeActivity
Create javadoc for the changes to the HomeActivity onStop() method.

Uncomment piece of code that had been out for testing purposes.
