Make investment filters easier to understand

So now:

* In the first few phases, no filters are shown (just like before)
* During the valuation phase, we show "Active" and "Unfeasible"
* During the final voting, we show "Active" (which now refers to the
  selected investments), "Not selected for the final voting" and
  "Unfeasible"
* When the budget is finished, we show "Winners", "Not selected for the
  final voting" and "Unfeasible"

Now each investment is shown in one (and only one) of the filters
(except when the budget is finished; in this case we don't show selected
investments which didn't win), and we remove the confusing "Not
unfeasible" filter by only showing it during the valuation phase (before
filters are selected) and renaming it to "Active". We also rearrange the
filters so the default one for each phase is shown first.

The idea of using the "Active" text for investments which can be
selected during the selection phase and voted during the final voting is
experimental. Right now, for simplicity, since we assume filters will
always use the same text, we're removing the "Active" filter when the
budget is finished, since having both "Winners" and "Active" filters
would be confusing.
