Add support for AND/OR indications for the rules in a filter

Matching multiple descriptions while only checking for a single account is currently not possible without this feature.

@Crecket Would suggest also adding a NOT/unless/except. :) That way, say you have a shared account with someone. You don't want in/outgoing payments between your own accounts to count towards in/out for the statistics.

Eg: You want to make filters to create ease of overview for various subjects. Every month, you put €500 each in to the shared account, and sometimes you accidentally send too much or need something back: so you sent a part back to your own account. You do not want to count these transactions to the total. So you can say "All transactions from and to account X should count towards the "Together" category, except for when it is a payment to/from , ".

Just an idea. :)
