[Vala] gtkaml 0.4.0 released with Gtkon syntax

[Vlad Grecescu <b100dian gmail com>]

Hello,
I am proud to announce the 0.4.0 version of Gtkaml introducing the new
Gtkon syntax.

Gtkaml is a markup language based on Vala which lets you create Gtk+
composite widgets through concise XML:

<HBox homogeneous="false">
      <Label label="_Hello" with-mnemonic="true" expand="false" fill="false"/>
      <Entry g:public="my_entry" text="World! "/>
</HBox>

Gtkon is an object notation alternative to the XML syntax, contributed
by pancake at nopcode.org:

HBox !homogeneous {
  Label with-mnemonic label="_Hello" !expand !fill;
  Entry $my_entry text="World!";
}

More information on the Gtkon syntax is available here
http://code.google.com/p/gtkaml/wiki/Gtkon and in the tests and
examples gtkaml comes with.

Changes in gtkaml 0.4.0:
- [breaking] signal values are by default references to methods, and
generate lambda body only when enclosed in braces (behaviour is
reversed wrt gtkaml 0.2.x)
- Fixed Issue #22 "can't find class with nested namespace" - fix by herodjar
- gtkaml builds with vala-0.10.1 and vala-0.12 from HEAD and so it
does not distribute .c/.h files anymore
- added support for run_source with the `gtkaml' command (the source
cannot start with #! yet)
- added the --write-vala (-V) switch which stops gtkamlc right after
generating vala files.

Features:
  * compact XML syntax for describing composite Gtk widgets
  * Gtkon syntax for JSON-like sources
  * code 'islands' (written in Vala) - for signal handling and other
code in your widget class (so you don't modify the generated code
ever)
  * you don't depend on gtkaml at run-time
  * much more readable than the usual UI boilerplate (e.g. you don't
need to worry about temporary variables, or ever write hundreds of
lines of code)
  * works with any library that has a .vapi file, not just Gtk+
(composition methods can be specified in the *.implicits file)
