Game framework done

The concept of the game is now done. Images are being swapped depending
on how long the game has been running. To get an animation between the
image swaps, an image with lower opacity is being drawn over the current
image. The opacity of the covering image depends on how much time it is
left until the image is being swapped.

For testing purposes, the background color is being changed to black
when the time is up and gray when the correct word is typed.

It is also possible to use spaces in the answers. The spaces will not
generate a word button.
Added image loading from localhost

The images are now loaded in real time from the localhost on my
computer. This was mainly a test since the images cannot be loaded in
real time later.

The bug where the opacity of the covering image was not changed has been
fixed.
Moved image loading to a background thread

When the application is started, a yellow screen is shown. When touching
the screen the Game Activity starts and loads the images in an Async
Task. When this is done, the game starts.

When the correct word has been guessed, the image immediately gets
unblurred.
