This change cleans up the JavaDoc in SearchableInfo,
removes trailing whitespace, fixes an if-statement
style violoation, and re-hides some things that were
exposed for Froyo that query deprecated or discouraged
attributes:
SearchableInfo.getSearchButtonText()
SearchableInfo.getLabelId()
SearchableInfo.getIconlId()
class SearchableInfo.ActionKeyInfo
SearchableInfo.findActionKey()
