Split single gitweb.js file into smaller files, each dealing with
single thing. This should make gitweb's JavaScript code easier to
maintain.
For better webapp performance it is recommended[1][2][3] to combine
JavaScript files. Do it during build time (in gitweb/Makefile), by
straight concatenation of files into gitweb.js file (which is now
ignored as being generated). This means that there are no changes to
gitweb script itself - it still uses gitweb.js or gitweb.min.js, but
now generated.
