Simplify templates about jbake-example-project-thymeleaf

[jonbullock]

Hi Peter,

Absolutely fine with me.

[msgilligan]

There are also three templates (index.thymeleaf, archive.thymeleaf, tags.thymeleaf) where the th:with is not used, resulting in bad links like: nullarchive.html. I was going to submit a PR that added three more instances of:

th:with="rootpath=(${content.rootpath != null} ? ${content.rootpath} : '')"

in order to correct that.

@pitpalme Do you have a pull request to simplify that (by defaulting to '' elsewhere) or should I go ahead and submit an (easier for a JBake beginner) PR that just modified the three template files to contain the redundant code?

Update: In tags.html, rootpath needs to be defaulted to '../' to work correctly -- and there's an even worse problem with the includes. Looks like this really does need to be solved in the (Java?) code that initializes content.rootpath

Hi Sean the default value for rootpath should be ../ when rendering the tag files, that's set here: https://github.com/jbake-org/jbake/blob/master/src/main/java/org/jbake/app/Renderer.java#L233

Is this not the case?

I think my problem was caused by using version 2.4.0 of the bake command-line tool to initialize the project assets/templates/content, but configuring JBake 2.3.2 in my Gradle file. I created another project later using 2.4.0 consistently and did not have the problem.

@pitpalme any progress on the PR? I'd greatly appreciate a more up2date version of thymeleaf templates in the upcoming new release of jBake. Thanks
