Add support for prefix and gitsrc arguments to 'make'

This should improve the installation a little, especially since the new
options are mentioned in the README. Also, add a make-rule to build the
git binaries if necessary + a dependency between cgit and libgit.a.

                        cgit - cgi for git
 
 
 This is an attempt to create a fast web interface for the git scm, using a
 builtin cache to decrease server io-pressure.
 
 
 Installation
 
-$ $EDITOR Makefile
-$ make
-$ sudo make install
+  $ make gitsrc=<path>
+  $ su
+  $ make prefix=<path> install
 
-Note: cgit requires the git and xdiff libraries. Currently, the makefile
-expects these files to be found in '../git/libgit.a' and '../git/xdiff/lib.a',
-where they will be if you have built git from source in a parallell directory.
+
+Default value for gitsrc is "../git", and this directory should contain the
+git sources.
+
+Default value for prefix is "/var/www/htdocs/cgit". This directory will 
+contain "cgit.cgi" and "cgit.css" after 'make install'.
+
+After installation, httpd.conf probably must be updated with a Directory-
+section for cgit, possibly something like this:
+
+  <Directory "/var/www/htdocs/cgit/">
+      AllowOverride None
+      Options ExecCGI
+      Order allow,deny
+      Allow from all
+  </Directory>
 
 
 Runtime configuration
 
-The file /etc/cgitrc is read by cgit before handling a request. A template 
-cgitrc is shipped with the sources, and all parameters and default values 
-can be found in this file.
+The file /etc/cgitrc is read by cgit before handling a request. In addition
+to runtime parameters, this file also contains a list of the repositories 
+displayed by cgit.
+
+A template cgitrc is shipped with the sources, and all parameters and default
+values are documented in this file. 
 
 
 The cache
 
 When cgit is invoked it looks for a cachefile matching the request and 
 returns it to the client. If no such cachefile exist (or if it has expired), 
 the content for the request is written into the proper cachefile before the
 file is returned.
 
 If the cachefile has expired but cgit is unable to obtain a lock for it, the 
 stale cachefile is returned to the client. This is done to favour page
 throughput over page freshness.
 
 The generated content contains the complete response to the client, including
 the http-headers "Modified" and "Expires".
