Fixed callSuperMethod()

It would not have worked the old way if it was actually called with at least one object, because the getMethod() method needs the Classes.
All calls are without passing any argument, so it is not necessary here to deal with this case.
Fixed hook to show Toast that the Video was saved to the SD Card.

The UI was heavily changed with the new release of Snapchat 3, so the "showVideo" hook now has to target the "ui.SnapView" class. It now receives a Context Object as an argument.
Updated AndroidManifest.xml to new version 1.3 (code version 4)
Added sensible .gitignore file
Run mediascanner, only for images though
MediaScanner video support! (+ some imports I forgot)
Optimize code and imports, added comments.
Improved video saving toast and media scanner.

 If the video path is empty, show an error, otherwise show a toast that the video saving was successful and call the media scanner.
Version bump 1.4

Media scanner added. Video saving toast improved: Now showing the path or displaying an error
Delete note saying that screenshotted is reported...

...as this is no longer the case since the v1.3-silent release.
Fixed double saving.Check if image file already exists. Don't resave in this case.
ver1.4.1 bump.

-fixed double saving of the image
dummy settings screen as main activity
removed period from preference texts
added out/ folder to .gitignore
added OnSharedPreferencesChanged Listener

Now the summary text under the ListPreference items will always reflect the current selection.
Load the SharedPreferences in the Keepchat class

...and added check for whether images or videos should be saved at all.
A dialogue for asking whether the image or video should be saved is not implemented yet.
Added out/ to .gitignore
Comments improved. Also use more javadoc.
