[Testing] Calculator Version

[Mikus Grinbergs]

> I need to find the version of calculator in my OLPC

Simple procedure:

 * Restart Sugar (e.g., ctl-alt-erase):  This is in case the version of
   the Activity has changed since the last time Sugar was started.

 * Home View List - Version number will be given next to Activity name
   (the search field can help if you have many screens of Activities)

More Complicated procedure:

 * (This assumes all activities are located via /home/olpc/Activities):
   In Terminal enter 'cat /home/olpc/Activities/Calculate.activity/
   activity/activity.info' (all one line) and look at activity_version.

Note:  occasionally, authors will have (by mistake) released more than
one version of an Activity, all with the same Version number.  Then you
will NOT be able to tell what you have (from the version number itself).
