Redo transaction types and titles

 
Store original title and statistic in xml, translate to string when showing gui and export
  * less data to store
  * support changing language

Breaking change. Will not work for transactions already saved.

```
MoneyType:: BOUGHT_MATERIALS :: 
MoneyType::     id :: 37
MoneyType::     title :: finance_other
MoneyType::     statistic :: expenses
```
