endpoint. (%static-directory, file-mime-types): New variables. (url-handler):
Add handler for “/status/<repo_name>â€; add handler for static files.
Implement first feature. Add bootstrap style.

functions: evaluation-info-table, build-eval-table, pagination.
* src/cuirass/database.scm: Add new requests to database:
db-get-evaluations-info, db-get-evaluations-count. Add evaluation filter to
db-get-builds.
* src/cuirass/http.scm (url-handler): Change "status" endpoint to
"/". Add endpoints: ("jobset" name), ("eval" id).
Change HTML5 to XHTML. Fix codestyle.
* src/cuirass/http.scm (respond-html): Add XHTML preamble and
content-type.

request.
Update id pagination (previous+last buttons).

* src/cuirass/database.scm(db-get-evaluations-build-summary):
Implement different order for low and high borders.
Add pagination for each evaluation page.
* src/cuirass/templates.scm (build-eval-table): Add pagination.
* src/cuirass/database.scm: Add border filters for pagination in
db-get-builds. Add functions for searching max and min stoptimes.
* src/cuirass/http.scm: Add pagination parameters in "eval" query.
Fix codestyle.
* src/cuirass/templates.scm: Fix codestyle.
* src/cuirass/database.scm: Fix codestyle.
