Unify getText and getTextFormatted behaviour

[TadeasKucera]

As of now, the methods getText and getTextFormatted have different behaviour. The getTextFormatted method returns a text which is nicely formatted while getText returns the same content but formatted differently - not very easy to read.

Some users tend to use getText instead of the getTextFormatted method but expect to get the nicely formatted output. For this reason, we would like to make getText alias of getTextFormatted, so both methods would return the very same thing.

At the same time, we would like to introduce a new method getTextUnformatted, which would replace the current getText method. This method would not be mentioned in the documentation and would only help us with debugging.

After a few months, we would remove the getTextFormatted method and force all our users to use getText method only.
