[PATCHv7.1 4/4] gitweb: Minimal testing of gitweb caching

[Jakub Narebski <jnareb@gmail.com>]

Add basic tests of caching support to t9500-gitweb-standalone-no-errors
test: set $caching_enabled to true and check for errors for first time
run (generating cache) and second time run (retrieving from cache) for a
single view - summary view for a project.  Check in the
t9502-gitweb-standalone-parse-output test that gitweb produces the same
output with and without caching, for first and second run, with binary
or text output.

All tests, including those added here, passes.
