winspector.c: Full clean patch

winspector.c: Full clean patch

This patch sets a correct style on winspector.c. It removes some
empty lines, moves variable definitions to the function heads,
moves preprocessor definitions to the top of the file and removes
some extra curly brackets.

The function to create the winspector panel is so big, and is hard
to understand it. This patch split the function createInspectorForWindow
in some extra functions:

create_tab_window_attributes
create_tab_window_advanced
create_tab_icon_workspace
create_tab_app_specific

This functions don't do nothing extra, only the code is moved to them.
