login: preserve GET arguments throughout login redirection (issue #104)
When redirecting a user to the login page and while handling this login and
redirecting to the original page, the GET arguments passed to the original
URL are lost through the login redirection process.
For example, when creating a pull request for a specific revision from the
repository changelog, there are rev_start and rev_end arguments passed in
the URL. Through the login redirection, they are lost.
Fix the issue by passing along the GET arguments to the login page, in the
login form action, and when redirecting back to the original page.
Tests are added to cover these cases, including tests with unicode GET
arguments (in URL encoding).
