.gitconfig: Add aliases to find branches/tags/commits

Closes #304.
bin: Make `httpcompression` prevent caching

In some cases, intermediate proxies ignore the `Content-Encoding` header
altogether.

Sending `Cache-Control no-cache` as a request header solves this problem
by forcing validation of the resources in the intermediate proxies,
thereby, ensuring that every request is fetched from the origin server.

Ref. alrra/dotfiles#2. Closes #308.
