Allow all trimSpaces options, and expose jar scan filter options.

[jpmsilva]

This PR exposes all trimSpaces options.
Previously it was a simple boolean, but Tomcat actually supports 4 different options - true, false, single and extended.
The default value if no other value is supplied remains false for backward compatibility.

Exposed configuration options tldSkip, tldScan and defaultTldScan that are passed to the jar scan filter that is used to process JARs that might contain TLD files. This can be used to speed up the build.

Finally, added support to redirect the JULI log API that Jasper uses to Maven's own log (SLF4J).
This results in a cleaner log trace for the build.

This has been released as 4.2.0. Thanks for the contribution!

Wow, that was fast!

While I don't anticipate any issues with the JULI log redirection, do let me know if there are any issues related to logging, as they might be related to this change. If so, I can probably introduce a goal parameter to enable/disable the log bridge behavior.

Related to this change, shouldn't the documentation site be updated?
I'm not entirely sure how/when that happens, but do let me know if there is anything else I need to do in order to reflect changes to the goal parameters.

Thank you!

Hmm, I actually pushed the updated documentation to the gh-pages branch but it seems to not have deployed correctly. I need to do more investigation.

[leonardehrenfried]

I took a look and I appeared to have misconfigured the site plugin so it doesn't produce the plugin docs anymore. Do you know how to do it, @jpmsilva ?

Hi @leonardehrenfried
I created PR #213 to fix that.
Further information regarding the change was added to it.
Hope it helps!
