debian: Fill in gecos field for jenkins user

Otherwise when Jenkins runs git, git will complain that the identity is
not set up correctly and will fail.
[JENKINS-3107] Expand an Advanced section if some fields are already customized.
Initial implementation handles only text fields, not e.g. checkboxes.
[JENKINS-3107] Rather than preëxpanding the Advanced area, just show an icon.
[JENKINS-3107] IE 9 fix.
[JENKINS-3107] Icon looks better before button rather than after, for reasons of alignment with the rest of the form.
[FIXED JENKINS-9637] Fixed the 404 when clicking the testResult on the Project Page when there is only an aggregated test result for a freestyle job. The name of the link is still wrong.

- set findbugs version to 2.5.2 to avoid:
[WARNING] 'reporting.plugins.plugin.version' for
org.codehaus.mojo:findbugs-maven-plugin is missing. ...

- delete maven-pmd-plugin and maven-checkstyle-plugin (commented out
since more than two years)
Close JarFile resources in PluginWrapper and UpdateCenter
Fixed Brazilian Portuguese translation of "Full Log".

The translation was too literal: the log is not full as in a cup of water (this is what "cheio" means), it is full because it is not a partial object.
Comment.

Does not make much sense to put @DataBoundConstructor on an abstract class.
(Stapler 1.218 rejects it, I think correctly.)
