Icon for web view activity.
Added menu xml file for lesson 9 (web view exploitation)
Added activity_lesson9.xml.
Updated activity selection with Activity 9
Lesson 9 currently appears in sliding menu on Android Virtual Device
(AVD) during testing.
Removed commented out code.
Currently stealing code from activity 1 to re-create challenge for web
view exploit.
buttons & titles oh my! 
[+] Currently edit text & instruction menu work. However, without the
use of the proper AVD (an AVD that has the challenge hard coded into it)
there's no way a user will actually be able to "complete this". Activity
9, may be better as a stand alone app or a small instruction menu. I
will continue with the instruction menu & edit text component.
Updated strings with activity 9's instruction menus.
R.java updating with the changes made to other .java files.
