Before this patch the non-TypeScript version of the slide mode causes
problems with the TypeScript code. Therefore, in order to get things
working, this patch does minimalistic changes to the slide mode
controller to bring it into TypeScript convention. And unbreak slide
mode. Further changes are required, but this gets slide mode back to a
usable state.

TypeScript considers null and undefined as fine for all variable by
default. This patch enables `strictNullChecks`, which should cause
errors to be thrown as soon as a variable is null or undefined without
having it explicitly decleared for itself.[1]

Because of circular import problems, this commit also moves the error messages from response.js to errors.js
