Title: Esc brings you back to the last buffer you were working on

closes #32
- creates b:this_buf to hold the vinegar buffer number
- creates b:last_buf to hold the alterate buffer number on startup
- creates a plugin function that switches to b:last_buf and deletes b:this_buf
- maps Esc to that Plug function
