Improve Adding Contacts

These changes provide more detailed instructions for adding contacts.

Users were confused by the process of adding a contact for the first time.
This change adds additional explanation and a picture of what is going on.

Closes #87

This change also shows the current step and the total number of steps when adding a contact.

Closes #33

The UI was transferred into XML files and lots of redundant code was deleted such as the custom CodeEntryView.

Please note that I did not implement a countdown for Bluetooth discoverability (#71), because of the way how the state machine resets the entire content view of the activity. This should probably be refactored to use fragments which would make the code cleaner and a permanent progress bar easier to implement.

Add Coding Style to git

This change adds the coding style file of AndroidStudio to git to be shared and used by all devs for a consistent coding style.

Feel free to adjust the coding style in case this does not properly reflect the current coding style used for the current code in all details.

File utils refactoring

After Ernir merged the two FileUtils implementations I realised two of the three methods are no longer needed and the third can just be a static method, like StringUtils etc.

This patch also fixes a layout problem with PasswordActivity on the Galaxy Nexus - the progress wheel was showing up in the wrong place. (You need a slow phone to notice!)

See merge request !12

Removed methods that are no longer needed for Java 6, moved the remaining method into the utils directory.

Improve how the status of messages is indicated.

Remove the Toast that always says 'Message Sent' and show graphical
indicators instead that show either:
* message is waiting to be sent
* message was sent (or requested to be sent)
* message was delivered

Please note that I didn't change the icons and did not migrate the UI to XML files to keep my change minimally invasive.

Closes #46

Don't mix JUnit 4's @Test with JUnit3's TestCase.

This is the world's most boring merge request. Android Studio was complaining about using JUnit 4's @Test annotations with JUnit 3's TestCase, so I fixed it.

Most of the changes come from Android Studio organising imports in a different order from Eclipse.

Create hidden service in a subdirectory. #161

The permissions for the parent directory are too permissive (775) for Tor 0.2.7.5. Store the hidden service hostname and private key in a subdirectory with permissions 700.
