This change broke spec filtering in Karma by changing the format of the
`spec` query parameter. Although karma-jasmine-html-reporter uses
jasmine-core's HtmlSpecFilter, karm-jasmine provides its own spec filter
that interprets the query parameters itself.
This feature may be reintroduced in 6.0 as a breaking change.
This reverts commit 8309416cb2.
- Will replace rake core_specs.
- Remove obsolete dependencies & files -- most of these were for build tasks we
are no longer using. Notably, rspec and spec_helper were deleted.
Similar to the changes in Jasmine core and console, this gets the
HTML specs of Jasmine using j$ instead of jasmine so that they use
the source files instead of the built distribution
