Data analysts should be able to use Text.split, Text.lines and Text.words to break up strings (#3415)
Implements https://www.pivotaltracker.com/story/show/181266184

### Important Notes

Changed example image download to only proceed if the file did not exist before - thus cutting on the build time (the build used to download it _every_ time - which completely failed the build if network is down). A redownload can be forced by performing a fresh repository checkout.

Extend Aggregate_Spec test suite with tests for missed edge-cases to ensure the feature is well-tested on all backends (#3383)
Implements https://www.pivotaltracker.com/story/show/181805693 and finishes the basic set of features of the Aggregate component.

Still not all aggregations are supported everywhere, because for example SQLite has quite limited support for aggregations. Currently the workaround is to bring the table into memory (if possible) and perform the computation locally. Later on, we may add more complex generator features to emulate the missing aggregations with complex sub-queries.

Use .isEmpty() instead of .length() == 0 (#3314)
Minor nit - since String is a CharSequence it's advisable to use the
corresponding method for checking the condition rather than writing
it by hand.
