+ Only install keystrokes.cfg when in full mode.
  + Only install nxproxy wrapper when in lite mode.

Provide a default keystrokes.cfg in /etc/nx (for nxagent) and /etc/x2go (for x2goagent). (Fixes: #199).

Fix faulty symlink path. Make sure that x2goagent symlink does not point to absolute path somewhere within the build environment.

This reverts commit e77bf36d.

Add Jan's reasoning for using string_rep() instead of bash based string substitutions as comment to /debian/Makefile.replaces.sh.

Main Makefile: Use absolute symlink when linking from $(X2GOLIBDIR) into $(NXLIBDIR) (i.e. linking x2goagent -> nxagent). (Fixes: #143).

Work-in patch from Jan Engehardt for working around different improper bash implementations of string-in-string replacing. (Fixes: #145).

Avoid building of libxcomp1 (which actually is identical to libxcomp3, just with a wrong name). (Fixes: #104).

Continue Reinhard's work on top-level install/uninstall. Esp. integrate debian/post-nx-build.sh into main Makefile. Make value of CONFIGURE variable traversable through the Makefile tree.

fix lintian: missing-separator-between-items in x2goagent depends field between nxagent (>= ${source:Version}) and ${misc:Depends}

No longer add them as quilt patch, as they are much easier to edit this
way. This, of course, requires adjustments to the roll-tarballs.sh script

The closes syntax is meant for Debian bugs. This avoids a lintian
warning during package build.
