Deleting obsolete encodeAllInputs function

[jglick]

As demonstrated in jenkinsci/workflow-cps-plugin#7, newer versions of HtmlUnit (which the 2.x plugin POM will pick up; cf. #390) will go berserk if they encounter a <script> directly inside <table> (i.e., between <tr>s). Always keep script inside <td> if you need it. This patch allows some configRoundtrip calls to succeed when using GitSCM.

In this case, the encodeAllInputs function seems to have not been used since 2.0: 61bd032 and 2d37646 deleted some usages but not the function itself. Anyway modern form binding does not require plugins to write JavaScript hacks like this. Just use field attributes, FormValidation with @QueryParameter and @RelativePath.

🐝 Looked for more calls of encodeAllInputs but there weren't any indeed.
