Support widget groups

[karlduderstadt]

This add support for widget groups. Strings with a GROUP visibility become group labels. Group members are annotated using the group annotation with the same name. The expanded annotation on Group label determines whether group members are showing or hidden initially.

@Parameter(visibility = ItemVisibility.GROUP) privateStringbasic = "basic"; @Parameter(group = "basic", label = "Number of ducks") privateintduckCount = 1; @Parameter(visibility = ItemVisibility.GROUP, expanded = false) privateStringadvanced = "advanced"; @Parameter(group = "advanced", label = "Advanced duck typing") privatebooleanadvancedDuckTyping = true; @Parameter(group = "advanced", label = "Starvation threshold") privateintstarvationThreshold = 6;

and in scripts

#@ String (visibility =GROUP, value ="basic") basic #@ Integer (label ="Number of ducks", group ="basic") duckCount #@ String (visibility =GROUP, value ="advanced", expanded =false) advanced #@ Boolean (label ="Advanced duck typing", value =true, group ="advanced") advancedDuckTyping #@ Integer (label ="Starvation threshold", value =6, group ="advanced") starvationThreshold

This PR requires changes in the Support widget groups to resolve #310 which is PR #428 at scijava-common -
scijava/scijava-common#428 until those changes are merged and scijava-ui-swing depends on the new version of scijava-common CI will fail here. This resolves issue scijava/scijava-common#310
