Language list in config dialog incorrect on first run

[Matthew Gates]

When changing languages, sometimes the tabs in the config dialog get all messed up. It's minor as it is an unusual use case to be frequently changing app language.

Also, when running for the first time, and language defaults to English, but Afrikaans is the value selected in the language combo box in the config dialog.

If English is explicitly set and the settings saved, this problem does not re-occur.

[Matthew Gates (matthew-porpoisehead)]

Language combo defaulting to Afrikaans appears to be caused by ConfigurationDialog.cpp:106 return value of StelApp::getInstance().getLocaleMgr().getAppLanguage() being "".

This doesn't make much sense because the application clearly does have a language, albeit the default one.

There should be a separate "System default" option.

Anyway:
- the bug lists two separate problems;
- the first one is duplicate of this one: https://bugs.launchpad.net/stellarium/+bug/683255

Ah good, so from this bug drop the language change issue.
