Do not include .htaccess or robots.txt in build #887

The build script should exclude .htaccess and robots.txt from the build, to not overwrite the user's local configuration.

e.g.,

• http auth access
• session.auto_start=0 (#881)

I don't think there is any .htaccess in the build, appart from the one in config/ that is there for security purposes and should not suffer / overwrite a configuration.

The robots.txt is necessary otherwise the error.log/access.log gets full of 404 errors when bots try to load the robots.txt which has been an issue reported by several users in the past.

Quite right, I forgot ./.htaccess wasn't under version control.

re: robots,txt. I agree it's convenient, but the flip side is that (a) unzipping into an existing installation will overwrite local mods and (b) it isn't used when piwik is installed in a subfolder, eg http://example.com/piwik
