Finnance possible improvements

[zazallegri]

• Total of all accounts by day, month, etc

• Set transaction in the future (not only present and past)

• Set monthly and/or yearly limits, for one or multiple (added) categories.
  Example: Added expenditures of categories "museums" + "cinema" should not exceed 20.-/month and/or 100.-/year

• Allow to search for categories (not only drop down menu) when adding a transaction
