Use `request.file("form-field-name")` to try to find a multipart-encoded
form value for the given name. Returns `jetzig.http.File` if a match is
found which provides `content` (uploaded file content) and `filename`
(filename as passed by browser).
Add `jetzig test` command which runs build step `jetzig:test`.
Add `jetzig.testing` namespace which provides test helpers and a test
app.
Add tests to view generator (i.e. include tests for generated routes).
Allow middleware to resolve a request by calling `request.redirect` or
`request.render` - after this point, the request stops processing and
renders immediately.
Permit setting template during view render with `request.setTemplate()`
Permit middleware to define custom routes to static content with
`pub const Routes` (implemented for something no longer needed but seems
useful anyway).
Implement globbing on custom routes, `/foo/:bar*` will glob all path
segments including and after `/foo/...`, e.g. `/foo/bar/baz/qux` will
pass invoke the custom view function with an array of `bar`, `baz`,
`qux` as first argument (instead of typical resource ID).
In `main()`:
```zig
app.route(.GET, "/custom/:id/foo/bar", @import("app/views/custom/foo.zig"), .bar);
```
Routes `GET` request with path (e.g.) `/custom/1234/foo/bar` to `bar()`
defined in `src/app/views/custom/foo.zig`.
Routes with an `:id` segment expect a function with three parameters,
routes without an `:id` segment expect a function with two parameters
(i.e. the same as `get` vs `index`).
Use Karl Seguin's http.zig as HTTP server backend:

Update loggers to use new `jetzig.loggers.LogQueue` to offload logging
to a background thread.
Numerous other optimizations to remove unneeded allocs.
Performance jump on a simple request from approx. 2k requests/second to
approx. 40k requests/second (Intel(R) Core(TM) i7-6700K CPU @ 4.00GHz).
