Update to 1.1.1:

This minor maintenance release mostly provides the usual collection of
janitorial cleanups and build configuration improvements.

It also changes the installation path for the pkg-config xbitmaps.pc from
$(libdir) to $(datadir), as no libraries or compiled code are found via
this pkg-config file, only platform-independent image files (which double
as C source code headers that programs may #include at compile time).
