Revert "Uses non-modal window for Crowdin authorization"

This reverts commit 33373e470022bf94f103caabae0ba1f751bd23c9.

It wasn't functional under wxGTK where having a modal window prevent
keyboard input into the non-modal browser window shown later. Arguably,
this worked on wxMSW mostly by accident anyway.

Keep using wxDEFAULT_FRAME_STYLE instead of wxDEFAULT_DIALOG_STYLE,
though, to make the browser window resizeable and generally behave like
a normal window.
