More preset enhancement ideas

[anonymous]

1. Allow length of input box for text: <text key="somekey" text="Something" length="5"/> : done in r5579
2. Label units at end of text input box: <text key="somekey" text="Long" unit="m"/>
3. Make groups of input boxes <group><text xxx/></group> and allow for several columns within a group (<group columns="3">)
4. Maybe allow in absurdly huge presets to minimize groups : treated with #9190
5. Radio buttons for checks that have two or more true values, or even where different choise migth alter the key:
   <radio text="Name"><button key="somekey" value="somevalue" text="A choise"/><button key="somekey" value="someothervalue" text="Another choise"/><button key="someotherkey" value="somevalue" text="A third choise"/></radio>: see #4901
