Remove useless @version documentation

[h-man2]

Describtion This issue solely improves the source code. In many files an old javadoc annotation @version $ProjectVersion: 0.393 $ can be found. This annotation is useless, because the version information is from an old version control system. Further, the information provided by the tag @version is more or less useless in the context of USE, because it can be extracted from the git history.

Expected behavior Remove all occurences of strings given by the regex ^.*\*.*@version.*\$.

[h-man2]

Additional cleanup:

Remove lines that solely contain // $Id$. Regex for this: ^\/\/.*\$Id\$\n\n (Note: two new lines to remove one blank line)
