41698518c9 Rename keyE to valJ and fix implementation. 
As Felipe points out in the PR comments, the implementation can be
simplified to "val . unValue" but the type signature on the function
still prevents anything non-sensical happening.

0b830771ea Add function keyE. 
Give a value, keyE lifts the Key for that value into the query expression.

    keyE :: Esqueleto query expr backend =>
            Value (Key entity) -> expr (Value (Key entity))

33b1fafc2d Thread IdentState through subqueries (fixes #28). 
There used to be name clashes if a subquery referenced
an entity that was already being used on the outer query.
Now we thread the outer query's IdentState to its subqueries,
which use it instead of initialIdentState.

Note that clashes still may occur between subqueries of
a query, but I think that's harmless.

b0329b05dc Use a bigger default chunk size when constructing the query. 
The default is 112 bytes, or 56 characters.  With this commit we
start using 992 bytes, or 496 characters, which should be enough
to fit most queries without needing reallocations or memory copies.

f718be86da Instead of using rawSql's Single, use a new data type Value. 
First of all, Value is a nicer name than Single.

However the main reason is to avoid error calls and to get better
feedback about the code from GHC.  Because of the GHC bug #6124,
we had many calls to 'error' just to avoid spurious warnings.  By
using data (instead of newtype) for Value we're able to avoid
them.  This commit removes *19* error calls from Sql.hs that GHC
is now able to prove that are unreachable.

f5c046775a Generalize types of numerical operations. 
Persistent doesn't ask for Num and everything has
worked very well so far.  Not having a Num constraint
also allows those operations to work on Maybes.
