bug: fix xml tag order

[DSCaskey]

This PR fixes the order of the groups and images XML tags. Instead of writing those tags as one of those resources is added, the app will now create the tags when the draftblock basepoint is created - maintaining the proper draftblock
structure.

<draftBlock name="Draft block 1">
    <calculation>
        <point id="1" mx="0.0520833" my="0.104167" name="A" showPointName="true" type="single" x="0.3125" y="0.416667"/>
    </calculation>
    <modeling/>
    <pieces/>
    <groups/>
    <images/>
</draftBlock>

This closes issue #1213
