Rename table crash_datas to crash_report_datas

Overhaul the repository link functionality - Fix regex (repositories with number or other characters were not accepted) - Url escape template arguments by default (the "do not escape" <%== $var %> markers can be used if needed) - Also support a generic repository type instead of only repotype:repopath in the configuration ($repotype:$repopath has priority over $repotype if both are defined) - Cache compiled templates

Require Mojolicious >= 5.81 for Mojo::Loader functional interface
