Add conditional builds for tools

[jamoore]

Currently the build system is hard-coded to build the only tool/ extension under licences/ (admin/ falls into another category -- GUIs). One should be able to control what is built under tools/ via a command-line property:

  java omero -DTOOLS=admin,licenses install

May need to use the iterator task from ant-contrib:

<!-- http://www.jguru.com/faq/view.jsp?EID=1099123 -->
    <!-- Import AntContrib -->
    <taskdef resource="net/sf/antcontrib/antcontrib.properties"/>

    <target name="main">
        <!-- Load the properties -->
        <property file="my.properties"/>
        <!-- Iterate over the list 'names.list' -->
        <!--   the 'inheritall' is important because otherwise      -->
        <!--   the loaded properties are not accessible by 'doName' -->
        <foreach list="${name.list}" delimiter="," param="name" target="doName" inheritall="true"/>
    </target>

    <target name="doName">
        <!-- Get the properties ${name}.* -->
        <propertycopy name="prop-1" from="${name}.prop-1" silent="true"/>
        <propertycopy name="prop-2" from="${name}.prop-2" silent="true"/>
        <!-- Set default values -->
        <property name="prop-1" value="default-1"/>
        <property name="prop-2" value="default-2"/>
        <!-- Use the values -->
        <echo> Derived values for ${name} </echo>
        <echo> prop-1 = ${prop-1} </echo>
        <echo> prop-2 = ${prop-2} </echo>

With Ivy fixes, build has improved beyond this. Closing.
