Subject: [PATCH] Add SHOESTRAP_BASE environment variable

This adds SHOESTRAP_BASE to helpers/default, which
allows the cookbook file to be stored separately from
the rest of the shoestrap stuff, making the shoestrap
directory less cluttered. For example:

Old way:

  (cd /shoestrap && ./test1.book)

New way (with cookbook moved to subdirectory 'books/'):

  (cd /shoestrap && SHOESTRAP_BASE=/shoestrap ./books/test1.book)
