[PATCH 0/5] git-gui: Support for "Locators" - address templates

This patch allows "locators" to be configured and used in the GUI, basically as URL templates the input string is subsituted into. The default operation of git-gui is not much affected (only some labels change to be less confusing).

This is aimed mainly at corporate Git deployments - the integrator might want to configure the central corporate repository store as the default locator so that people do not need to type the same URL over and over but can instead just type the repository name on the server. Or avid repo.or.cz users might set up a 'repo' locator pointing at 'git://repo.or.cz/%s'.

In practice, this seems to be a more significant usability improvement than it might seem. Less technical users appear to be less daunted to type in just the project name instead of dealing with long URLs.
