* utils/hbmk2/hbmk2.prg
+ Added .hbi to the list of accepted projects at cmdline.
This means that hbmk2 can be run like 'hbmk2 mylib.hbp mylib.hbi'
to create the lib and also generate the implib.
* '-keyheader=' renamed to '-reqheader='
! Fixed typo causing RTE while creating implibs for targets
supporting OMF lib type.
