FMSLogo Code

Update the installer to use the NSIS "Modern UI 2". Among other things, this has a richer UI, a configurable start menu shortcut dialog, and better support for a multi-language installer.

This also implements feature request #37, which is an explicit "done" page in the installation wizard.

Remove a cmd script that used to generate the version.h file. This is now done by the Makefile (for portability to GNU/Linux), so keeping this cmd script around is confusing.

Remove *.c from the source files which "tags" depends on. The Windows version of gmake has trouble with this because there are no .c files and it wants to make a literal '*.c'. And since there no *.c files (anymore) there's no reason for "tags" to depend on .c files.

Note that FMSLogo is entirely built using free (or zero-cost) tools,
now that the Borland OWL version has been removed from the tree.

Add text-decoration to all links so that it's more obvious what is clickable.
This was done mostly to make the links in the howtohelp page more obvious.

Update the HOWTO-BUILD.TXT to suggest only checking out the trunk
of the "logo" project (otherwise, checking out the files takes much
longer and the resulting directory is more complicated, as it includes
all branches/tags from all projects).

Fix the "test" target after refactoring the source code into a different
Subversion project than "extras". This change ensures that you don't need
the "extras" project checked out to in order to run "gmake test" on the
"logo" project.

Reorganize the directory layout in subversion to make logo, www, and extra
all separate projects, each with their own branches and tags, instead of
all being part of a single project with sparely populated branches and tags.

This fits better with how it was in CVS and how it should have been imported
into Subversion. It also fits better with the development lifecycle of each
of the separate projects.

Never refresh the background when refreshing an invalid rectangle on the screen. Since the entire rectangle is always refreshed, there's no benefit to refreshing the background as well--doing so only slows down the repainting and adds more potential for flicker. In truth, this change has little practical benefit.

Update the expected version to 7.0.0, in preparation for the next release.
