For some reason in the latest Qt versions the webview took over the
focus from the keyboard, once clicked on the webview the arrow
keys wouldn't register up and thus you couldn't navigate with them
anymore.
This patch fixes this problem by using window.location.href and
checkinf for those special urls. This is way easier to use than
WebChannels.
There was no feedback on any login errors when a user provided a
wrong url, username, password or a disabled API. This commit
adds feedback to the user in this cases.
Fixes#15
Untill now the MenuBar was not visible untill you pressed the
alt-key, which made it visible. Sadly after that it was not
possible to hide it again. This patch fixes that.
I have no idea why, I think it might be some timing issues while
initializing the webengine, but when using runJavaScript() in
the WebEngineView without referencing it with the id of that
QML object it just throws the error that it doesn't know what
runJavaScript() is. When we use the ID then it just works
for some reason.
