added some type checking / an error message to scan so it will fail a little more gracefully if passed bad arguments

added name of output variable error message to facilitate debugging (can someone who knows who the exception works push it into the text of the exception?)

Removed attempt at mimicing numpy behavior on mixed scalar-array operations, since this seems doomed

This one is not working either (committing it mostly to keep track of it in
the history).

characters.

division by 0)

and I'm calling directly the linker call_time is more close to what this
code expects.

Added the config md5 to the key of the generated C code, to make sure two config setups do not re-use the same C code by mistake

The exception raised when trying to use Mod on complex numbers is now raised in more such situations

Behavior of integer division can now be controlled with config.int_division, and the default value does not break code anymore

Added a simple test to test that Theano crashes when trying to do x % y with either x or y a complex number

Removed testing of Mod op on complex numbers (deprecated -- and maybe not working properly -- in numpy currently), to avoid a warning in tests
