Copyedit the license's revised text: (1) remove unnecessary repitition use of the word 'license' from the top of the header and source files (2) add the standard 'we hope it's useful, but no warranty' clause to COPYING (3) make explicit that linking OpenSSL is allowed (see https://people.gnome.org/~markmc/openssl-and-the-gpl.html for background) (4) sync the Qt and GTK+ clients' license popups with COPYING's revised text

* It may be used under the GNU GPL versions 2 or 3
Licensing changes: 1. add the option the code to be used under GPLv2 or GPLv3; previously only GPLv2 was allowed 2. add the "proxy option" as described in GPLv3 so we can add future licenses without having to bulk-edit everything again :) 3. remove the awkward "exception for MIT code in Mac client" clause; it was unnecessary and confusing.

Adjust uncrustify config, reformat all but Mac client There're places where manual intervention is still required as uncrustify is not ideal (unfortunately), but at least one may rely on it to do the right thing most of the time (e.g. when sending in a patch). The style itself is quite different from what we had before but making it uniform across all the codebase is the key. I also hope that it'll make the code more readable (YMMV) and less sensitive to further changes.

Align type qualifiers to the right (code style) This way all the qualifiers (`const`, `volatile`, `mutable`) are grouped together, e.g. `T const* const x` vs. `const T* const x`. Also helps reading types right-to-left, e.g. "constant pointer to constant T" vs. "constant pointer to T which is constant".
