changes to dashboard weren't saved anymore when changing series selection

* Do not hide select box for metric selection

* update screenshots

* Fixes memory leaks in dataTable and jqplot via uncleared resize handlers

Previously, these plugins registered a handler on the `resize` event on window,
but used ad-hoc heuristics to determine when to remove the handler:

* dataTable would only remove the handler the next time the `resize` event fires,
  which is not guaranteed to happen regularly (especially if the user is not
  regularly resizing their browser window, e.g., it is full screened)
  * Fix: I define `_destroy` on `dataTable`, which appropriately cleans up the
    handler (and calls the `_destroy` method of its parent class, `UIControl`)
* jqplot contained code to remove the `resize` listener when `destroyPlot()`
  is called, but a) this function is not called when the plot is removed from
  the DOM (the code called `destroy()` on the `plot` object directly), and
  b) it incorrectly uses `this` instead of `self`, preventing it from working
  in the first place.
  * Fix: I fixed the `this`/`self` confusion, and changed the cleanup code
    such that `$.jqplot.visiblePlots` contains `JqplotGraphDataTable` objects
    rather than `jqplot` objects.

These event handlers prevented previous jqplot and datatable objects from being
garbage collected each time the dashboard is refreshed.

* Prevent leaking data tables via body mouseup handlers.

Adds code to clean up mouseup handlers on the body HTML element when data tables are destroyed.

Previously, these handlers caused data tables to remain in memory forever.

* When a datatable is manipulated in memory, the correct id subtable is stored in metadata and must be fetched from there.

Signed-off-by: Stefan Weil <sw@weilnetz.de>

* Implement the UserId module, that adds a new Users report showing all unique user IDs and some aggregated data. Includes reindexing of raw visitors log into aggregated user ids table

* Use an injected model instead of creating a new object

* Rework the UserId plugin to use core archiver instead of custom indexer

* Users report small changes:
- remove logger injection
- change archive record name
- add low population filter

- add datatable_archiving_maximum_rows_userid_users configuration, default value is 50000

* Remove unused method parameter
