Double quote character not accepted by keyboard

[Matthias Schoettle]

The double quote (") is not located on the onscreen keyboard and also not accepted when typed on a physical keyboard.

This is problematic when an execution statement such as the following is required:

System.out.println("foo")

[Matthias Schoettle]

I propose to remove the back slash () from the keyboard, move the slash (/) to its position and the double quote character to the previous position of the slash.

[Matthias Schoettle]

Resolves #339: Removes bach slash and puts the slash to its position. Adds the double quote to the previous position of the slash.

If ever the back slash is needed, the method allowCharacter can be called to additionally allow other characters that don't fit on the keyboard.
