[mono-android] WebView goes full screen when in tab layout

[Craig Dunn]

>>I did have to change BaseActivity to Activity
Oh, sorry, BaseActivity is a custom class in my project - I forgot to
sanitise it out (sorry for any confusion).

Not really sure I know "why" the WebView behaves this way, except to say
that it does give you a lot of flexibility to decide how to handle Url
loading within your app (to intercept actions and control what is loaded).
Incidentally, I *think* if you had chosen a URL that does NOT redirect (you
put LoadUrl("http://www.google.com") in your example) then the WebView would
have probably loaded successfully "in" the tab with your original code - but
then any link you clicked would still have popped-out to a full webbrowser.
The reason the code below helps is because it traps those redirects and
forces them into the same WebView which is normally the behaviour you want.
