Fix IRR calculation of client

Previously, the client performance was *attempting* to adapt the yearly
IRR to the reporting period. That does not work. Keep IRR as calculated.

Issue: #80
Fix: export asset class types as translated string

The import already expects the readable, translated string. The export
should generate output immediately readable by the import.
Remove obsolete test

The test checked that the IRR was adapted to the reporting period.
Adapting the IRR that way does not makes sense. Code was removed already,
test is removed now.
New feature: Investment Plan

Investment plans allow the automatic generation of
recurring portfolio transactions - either as a BUY
or as a DELIVER_INBOUND transaction.

The editor enabled the user to manage his or her
investment plans and edit the resulting transactions.
Bump up Client version number to reflect changes to XML format

If the version number is not changed, old clients will not notice
that the format changed. When loading older formats, the 'plans'
member variable must be initialized manually (Xstream leaves it null).
Remove obsolete investment plan dialog
visibility in NewPlanDialog
removing sorters and blank lines
removing InvestmentPlanController

no longer needed, functionality is within InvestmentPlan
InvestmentPlan properties to report changes

Avoid pre-selection of account/portfolio when not known

The buy/sell/dividends dialog should not preselect the first account or
portfolio when opening the dialog as it leads to easy erroneous entries.
Preselect only if just one account or portfolio exist.

no "period" property. The day of the month is taken from the start date.
renaming "generateAccountTransactions" to "isBuySellEntry".
simplifying generateTransactions by ignoring the Transactions already
present in the portfolio but not in the plan.
