multiline strings containing end-of-line or beginning-of-line whitespace.

Open the store before constructing EvalState.
...
EvalState requires the `store` global to be initialized before it is constructed
in some cases, e.g. when it needs to download a tarball for something in
NIX_PATH. Hence, this fixes #13 .

Add sugar for defining a variable
...
‘x = <expr>’ is short for ‘:a { x = <expr>; }’. Note that the
right-hand side refers to the original scope, so you get:
nix-repl> x = 1
nix-repl> x = x + 1
nix-repl> x
2
rather than an infinite recursion.
