From Chris Wiebe
This patch makes sure the class wizard works as long as the selection
supports IAdaptable. It also prevents the class wizard from attempting
to generate new source files without a valid source path.
2004-04-13 Andrew Niefer
fix src/org/eclipse/cdt/internal/corext/template/default-templates.xml to restore changes lost in
string externalization (restore for loops to use preincrement)
