[JENKINS-14155]Use the lastest changed tag as default

[MichaWiedenmann]

In a recent commit (5012326e8dc523e5e7706839b7853a86b1f3dce5 - [JENKINS-14155] Automatically select the first option of tags listing…"), support was added to select the latest changed tag as default value. For this to work, the repository URL (of the subversion tag parameters) must point to the tags directory (e.g. foo/tags). If you want to also include trunk and branches (i.e. setting the repository URL to foo/), you cannot benefit from the "use the latest tag" feature.

This branch extends the recent functionality, such that one can use a repository URL pointing to the top level directory (foo) while still using the latest changed tag from the tags sub directory as default.

To this end a new checkbox "Use latest tag" is added below the "Default value" text box.
