changeset: add changeset and issue tracker links

Closes #315
Refs #369

Every word-boundary delimited string of 12 or 40 characters from the
range [0-9a-f] is considered a changeset link. Clicking on it in the
repository explorer, will jump to the given changeset if possible.

Issue tracker links are enabled when configured in the tortoisehg
section of the configuration files. There are two keys: issue.regex
and issue.link. The first defines the regex to match when picking up
issue numbers, while the second defines the command to run when an
issue number is recognized.

You may include groups in issue.regex, and corresponding {n} tokens
in issue.link (where n is a non-negative integer). {0} refers to the
entire string matched by issue.regex, while {1} refers to the first
group and so on. If no {n} tokens are found in issue.link, the entire
matched string is appended instead.

Examples:

BitBucket:
issue.regex = #(\d+)\b
issue.link = http://bitbucket.org/<your project and repo>/issue/{1}/

Mercurial:
issue.regex = \bissue\d+\b
issue.link = http://mercurial.selenic.com/bts/
