Allow setObject(x,y,Types.INTEGER) if y is Boolean & added Boolean to SQL Keywords

Problem:
 - Boolean not on list of SQLKeywords (The JDBC CTS seems to think that
it should be)
 - setObject(x,y,Types.INTEGER) will throw exceptions if y is a Boolean.

Fix:
 - Added Boolean to Keywords list.
 - Added check in setObject() under Types.INTEGER to check if a boolean
is passed. True=1. False=0. Is consistent with the rest of the code.

Cheers,
