routes: Implement support for categories

This changes the code so that in the routes we now build up the
repository path from the category and the name. If no category is
provided you simply end up with the name. This path is now used
everywhere a path to a repository is constructed which takes care of 80%
of making categories work. Handlers on the mux are added for the
category matching and reordered to ensure we hit the right entry first.

The new repository struct contains all info we need for a repository and
we default to allowing some fields to be empty if we can't retrieve the
information whereas previously we might've returned an error.

The entries is a single level tree of sorts that lifts the category, if
available, to be its name and otherwise uses the repo name. We can use
this to sort all entries alphabetically and now loop over them in our
template.

utils: Add helper to get all repos

This does a filepath.WalkDir of the config.ScanPath and tries to find
all valid git repos. It returns a list of repoInfo structs holding basic
information of each repository.

docs: Expand on repo.ignore

Make it clear the expectation is the paths are relative to scanPath.

config: Ensure we always have an absolute path

Having this consistent across the code is handy when we're building
paths, counting separators and other path manipulation.

readme: tiny thing

only add go meta import tag if go.mod exists in repo root

This is a multipart message in MIME format.

Pretty self-explanitory :3

sort tags and deduplicate

This sorts the tags reverse-chronologically.

If any tags have the same name (shouldn't happen but it does in some of my
repos), we use whichever one is "newer".

Link to parent commit file version in commit view

It makes sense for [oldfile] in [oldfile]->[newfile] to link to the
previous version. This is also how cgit behaves.

css: scroll file content x-axis only

- we don't need any overflow scrolling for the y-axis.
- set overflow-x to 'auto' so that the scroll bar only shows
  when the content does overflow.
