#196 better support for static libraries

[Chuck Simmons]

dev-c++ does not make it easy to automatically relink
an executable that makes use of a static library.

Possible types of solutions might include:

When using the project options to add a static library to
a project, have the makefile used to compile the
executable create a dependency of the executable on
the library;

or; make it easy (or document the functionality if it
exists already) to specify additional $(LINKOBJ) files.

But, really, when I specify that I want the library in the
project as part of the project options, the software
should figure out (or dialog with me) at that time to see
if I want the executable to depend on the library.
