msvc: kabc plugins

[Peter Kümmel]

in kabc/plugins are libraries and plugins with
the same name when compiled with msvc.

gcc uses different names because of the lib prefix,
(library: libkabc_file plugin: kabc_file)
but this does not work with msvc which never uses
a prefix.

So, what should I do to fix it?
Renaming the non-plugin libraries or
the plugin files?

Do other apps outside of kdelibs link against
the non-plugin libraries, or are they only used
by the plugins kdelibs?
