Changesets store author's id instead of committer

When a commit is authored by A and committed by B, Source_Parse_Users()
function incorrectly sets A's id instead of B's as the committer,
resulting in incorrect changeset information being stored in the DB.

Fixes #44
Simplify user-parsing code

Function Source_Parse_Users() was simplified by removing nearly
identical code to process the author and committer to a generic function
handling this task for both types of users.
WebSVN: fix broken links

Prior to this, every link to WebSVN (v.2.3.3) created unrendered
template pages. This changes URLs from 'websvn/action.php?path=&repo='
form to 'websvn/repo/path?op=' form.

Gitweb: Don't use PHP_EOL when parsing output

PHP_EOL is valid only for the current instance of PHP, while Gitweb is
perl and potentially running on a different architecture.  Filter CR/LF
explicitly instead.

Github: Wrong comparison of repository name

On Github the repository names are not required to be lowercase. The
repository name send in the payload-data by Github could be something
like 'RePo-SiTory_NamE'.

In that case the comparison will fail and no import is possible.

Fixes #34
