Added a file picker. Started implementing crypto. Atomic commits are hard
Merge remote-tracking branch 'origin/master' into FilePicker
Added encryption service with Conceal library
Added Bluetooth app sending (zip). Added hotspot creator
Did some renaming to make the name more appropriate for what the class does.
Added (not working yet) dialog for hotspot app sharing
Added dialog and extended menu. Http server still needs to be hooked up
Added Icons and changed naming
Fixed not allowed network names/passes. Added NanoHTTPD
Http server now runs on service. Notifications and all necessary things have been added. Not tested yet
Create StealthDialReceiver.java to receive phonecalls and intercept
those starting with #555
Extend StealthDialerFragment.java to display the phone number if it gets
created through this intent.
Change HomeActivity.java to always open the stealth Dialer Fragment.
Change manifest for right intents and receiver filters

Ignore all the other stuff. Somehow that's all changed too in the libraries and not sure why.
And if it should be ignored or not. Sorry about that.
Fixed filesharing over AP. Added NFC support (not tested yet)
Removed FileChooser library. Remove filepicker spike.
Fixed NFC permission. Reworking design of sharing activity. (might get thrown out entirely later on)
Removed useless PlaceholderFragment
Restructured passing of call data according to android specs
Made http server more general (intents can now be used to share every type of media)
Change StealthDialerFragment.java to update the phone number in the OnStart function so it gets updated on load. Still not the ideal interface. Looking into fragment reloading as that seems to be the proper way to do it I think.
Change HomeActivity.java so it can provide the last number used to open the app.

Added javadoc to StealthDialReceiver.java
Fix unclear variable name: stealth_number

the string stealth_number has been renamed to phone_number_dialed to be
clearer about what it contains.
