Clarify licensing
htop has been licensed as GPLv2 but there was inconsistency regarding the option to choose "any later version" as granted by the license. This commit clarifies the htop dev team is fine with that choice.

Import and use of headers
+We use the GPLv2+ as a shorthand indication that we release `htop` under the GNU Public license version 2 but are totally fine with users opting to apply the "any later version" clause.
Every file should import headers for all symbols it's using.
Thus when using a symbol from a header, even if that symbol is already imported by something else you use, you should declare an import for that header.
Doing so allows for easier restructuring of the code when things need to be moved around.
