1-Fixed javadoc snippet in order it recognize if it is documentation for a function
or a class. It also look now at the region from the cursor only, it avoids considering functions definitions BEFORE the cursor, without any
empty line between.
1-Added the return clause to javadoc snippet (Emacs/yasnippet).

I also reviewed the check-if-function test in order it doesn't fail when the parameters are on several lines.
1-Updated Emacs abbrevs.
1-Removed an unneeded message display in myantcompile.el (Emacs).
1-Added a command to start a jdb session from current Java source file buffer, executing the class defined in this file.

TODO: I'd like to set the jdb command in the command buffer without validating it automatically, to be able to modify it
if necessary, as it is for ant-*** command.
