attached is a little patch which cleans up the includes and improves
ordering of the included header files.
The main change is to include "geany.h" very early, this header will
implicitly include most of the GLib and GTK headers you need. So, there
is no need to explicitly include something like <glib/gmacros.h> which
is deprecated due to GTK's single header policy anyway. I don't want to
bore you with details, just make "geany.h" your first include in
general should do the trick.

In the future, i.e. once Geany 0.18 is released, things will get a lot
easier, then you only need to include "geanyplugin.h" which includes
most other necessary Geany and GTK headers.
The API docs, especially the howto describe this issue as well, IIRC.

While there are probably not many people out there (anymore) who use a
C89/C90 compiler, there are at least a few of them. And so we try to
keep the Geany code compiling with gcc -ansi, i.e. compatible with C89.
Nobody is forced to do the same with plugins, but it just makes it
easier for users. The current code still doesn't compile with a pure
C89 compiler because C89 doesn't allow to mix code and variable
declarations. Cédric, it's completely up to you whether you want to
"fix" this or just keep it as it is.

If you want to see the warnings I'm talking about, just check
http://nightly.geany.org/misc/build_gtk28_plugins_stderr.log tomorrow
(after August 11, 04:00 UTC). There should appear a few warnings. But
again, it's completely up to you whether to remove them or to keep them.
