Ability to change language on the fly

[Former user]

Originally reported on Google Code with ID 75

Additionally to system wide language settings, we should provide a way so
the user could change the language on request. That would be useful for
translation testers, people who's not using own machine, etc.

``` I have done something like this for other Qt applications. I can probably implement it once we're doing the trunk again. ```

``` OK, if you happen to do so then, please be aware of the new RTL language support. Something can end up broken if we're not careful. ```

``` On a side note: the KDE 4 interface should be able to do that natively, as that's a side benefit of using KApplication. ```

``` That's right! But I cannot thing of a way of keeping it to work with plain Qt without setting all strings in a single recallable function, as exemplified in the Qt tutorials. BTW, KDE probably also takes care of bidi automatically, which we must avoid because of math nature of the program, and do it by hand as currently done for the Hebrew translation. ```
