Add scaffolding for Table.write function (#3521)
Implements https://www.pivotaltracker.com/story/show/182309559

This task implements common scaffolding for the `Table.write`, so that the particular implementations for Delimited and Excel file formats can be done in parallel.

Cleanup Ref - get/put (#3457)
The change promotes static methods of `Ref`, `get` and `put`, to be
methods of `Ref` type.
The change also removes `Ref` module from the default namespace.
Had to mostly c&p functional dispatch for now, in order for the methods
to be found. Will auto-generate that code as part of builtins system.

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.

Aggregates in the Database library - MVP (#3353)
Implements infrastructure for new aggregations in the Database. It comes with only some basic aggregations and limited error-handling. More aggregations and problem handling will be added in subsequent PRs.

# Important Notes
This introduces basic aggregations using our existing codegen and sets-up our testing infrastructure to be able to use the same aggregate tests as in-memory backend for the database backends.

Many aggregations are not yet implemented - they will be added in subsequent tasks.

There are some TODOs left - they will be addressed in the next tasks.
