Links to definition in source code

[kiith-sa]

• Level 1:

  Definition at line 96 of module tharsis.entity.entitymanager.
                <LINE-LINK>        <MODULE-START-LINK>

  Or maybe a shield.io style image (or just HTML+CSS) link: [tharsis.entity.entitymanager|96] where the module and line part have different background colors, which change on mouseover.

  Will point to the source file relative to a root address specified in hmod.cfg.

  E.g. module-link-root = https://github.com/kiith-sa/tharsis-core/tree/master/source/ should work for GitHub, even with line numbers:

  https://github.com/kiith-sa/tharsis-core/blob/master/source/tharsis/entity/componentbuffer.d#L20

  Should also work with plain file paths (../source/) and without line numbers (to open plain D files).

• Level 2 (optional):

  Generate HTML-rendered source and allow linking to that instead of either an on-line repo like GitHub or a relative link to plain text files

Obvious, but note: do not generate links to source if the user does not specify a root path.
