Fix float-to-string to accept integers, fix #249.

Browse Source 
The problem in #249 is that SQLite is happy processing floats in an
integer field, so pgloader needs to be instructing via the CAST
mechanism to cast to float at migration time.

But then the transformation function would choke on integers, because of
its optimisation "declare" statement. Of course the integer
representation expected by PostgreSQL is float-compatible, so just
instruct the function that integers are welcome to the party.
