add missing Keys for the UI-apps.
Missing keys are (from what we know now):

Security-app:

• security.users.actions.deleteFolder.label
• security.systemUsers.actions.deleteFolder.label

StkSiteDefinitions

• stkSiteApp.browser.actions.move.label

StkThemesApp

• stkThemesApp.browser.actions.move.label

StkChannelsApp:

• stkChannelsApp.browser.actions.move.label

StkTemplateDefs.-App:

• stkTemplateDefsApp.browser.actions.move.label

JcrBrowser:

• websiteJcrBrowser.browser.actions.move.label

*.browser.actions.move.label is somehow systematic and we may have an error in fallback-strategy-keys. to be evaluated probaly with Christopher Zimmermann
