By covering our ears and ignoring as much as possible. Apparently SyntaxError is
not a subtype of Exception. Also need to send raw strings otherwise unicode
characters will cause fits.
Also added new command, `ein:pytools-reinject` to reinject ein's pytools code.
The name could probably use some work.
Python running on a remote connection doesn't know how to find files on the
local machine, apparently, so we take the route instead of sending the contents
of a temporary buffer loaded with the pytools python code to the running kernel.
