Subject: [PATCH] Infrastructure for tig rpm builds

Adds RPM_VERSION to Makefile and new make targets: tig.spec, dist, and
rpm. A simple 'make rpm' will build the rpm. Also adds tig.spec.in
which is used to generate tig.spec.

Accidentally VERSION (and adding -DVERSION=$(VERSION) to CFLAGS) is
now defined always, even if we do not compile from the "live" tig
repository.

Minimally tested (meaning "make rpm" from tig repository works).

+%description
+Tig is a git repository browser that additionally can act as a pager
+for output from various git commands.
+
+When browsing repositories, it uses the underlying git commands to
+present the user with various views, such as summarized revision log
+and showing the commit with the log message, diffstat, and the diff.
+
+Using it as a pager, it will display input from stdin and colorize it.
