Summary: if attribute on target should control dependencies as well

Initial Comment:
If the "if" attribute of a target evaluates to false it
will not be executed but all its depedencies will. The
dependencies should also be skipped.

hmm, indeed. the if attribute should be on userdoc (if we 
don't want it executed on mono, that is)

In that case NAnt.build is busted. The following :

<target name="install" depends="install-windows,
install-linux" />
    
    <target name="install-windows" depends="userdoc"
if="${platform::is-win32()}">

clearly doesn't intend to execute the userdoc target if the
platform isn't Win32.

I'm pretty sure this is "by design", and I think Ant also has 
the same behavior.

The reason is that you might want to determine whether a 
given target should be executed, in one of its dependencies.

eg.

<target name="build" depends="check-uptodate" unless="${is-
uptodate}">
    ...
</target>

<target name="check-uptodate">
    <!-- dependending on whether output is up-to-date, set 
property to true or false -->
    <property name="is-uptodate" value="true" />
</target>

I'll double-check this later (but not today, I think)
