New build system feature to shorten the turn-around times when working

Browse Source 
with image files. E.g.

  jam -q update-image libbe.so kernel_x86

will only build libbe.so and the kernel (if necessary) and copy them
onto the already existing Haiku image. The MIME DB will not be
reinstalled, and only those source directories will be copied for which
the AddSourceDirectoryToHaikuImage rule is given a second argument
(e.g. "1"). The image will otherwise remain unchanged.

The "update-vmware-image" and "update-install" work similarly for the
VMWare image and the directory installation respectively. Note that, due
to the way the VMWare image is created (prepending a header to the
standard image), the file itself is fully rebuilt, i.e. changes made
during the emulation will be lost after updating the VMWare image.

The feature requires Haiku's jam. With other jam versions a similar
effect can be reached by accordingly setting the HAIKU_IMAGE_UPDATE_ONLY
and HAIKU_INCLUDE_IN_IMAGE in the UserBuildConfig file.
