Title: Fix a “text is read-only” error when calling comint-previous-input in SBT buffer

This fixes an bug where the first time `comint-previous-input` is called at a SBT prompt, a “text is read-only” error message is displayed, the point moves to the beginning of the line, and the previous input is not entered. Caused by `comint-prompt-regexp` not matching the SBT project prompt.
