cspell fails on project names and four typos

Part of #3596034 (closed).

Problem/motivation

The cspell job reports 68 issues on 1.x. Most are names that cspell does not know: c2patool (read as patool), jrglasgow, phpseclib, routematch and the cscu query alias. Four are typos: Implments, integreate ith, objct and an presign.

Proposed resolution

Fix the typos and list the names in .cspell-project-words.txt, which the GitLab CI template reads.
