Subject: [PATCH] Options to include separate libraries in build

Added new options CONFIG_CHARSET and CONFIG_SHERLOCK_LIB to makefiles &
configure. CONFIG_UCW_ONLY now works only as a shortcut for excluding
all other libraries.

Updated libs-only distribution and libsonly custom to use these
switches.
