[tools] testbot/web: Use .errors files to highlight errors in full logs.

[Francois Gouget]

Instead of relying on Get*LineCategory() to identify error lines and 
only using the .errors information to single out new errors; JobDetails 
now uses the .errors file for both and only uses Get*LineCategory() to 
highlight warnings, informational messages, etc.
