Shared library numbering confusion

libkbase_wizard isn't a plugin, therefore

libkbase_wizard_la_LDFLAGS = $(all_libraries) $(KDE_PLUGIN) \
                                 -version-info 0:7:0


in libs/wizard/Makefile.am should be changed to

libkbase_wizard_la_LDFLAGS = $(all_libraries) \
                                 -version-info 0:7:0

This will make sure that -version-info is actually used and the library 
gets a soname, as is expected of shared libraries that are not plugins.

On the other hand, libkbase_driver_mysql is a plugin; therefore the 
following should be done in db/mysql/Makefile.am so that it does not 
get a useless version number:

 libkbase_driver_mysql_la_LDFLAGS = \
+       -avoid-version -module -no-undefined            \
        -L$(MYSQL_LIBDIR)
