Add sidebar
Avoid NPE in error controller
Add additional ViewResolver configuration

The DispatcherServlet adds a default InternalViewResolver
which was used by some apps, but when the actuator was
available it added an "/error" bean and effectively
switched off the default view resolver. The net fix was
to add an InternalViewResolver at the same time as
adding any other ViewResolvers.

[Fixes #55357516] [bs-290] Actuator UI app cannot serve static index.html
Remove commons-logging dependency for starter projects
Restore Tomcat in CLI

Seems to work. I think the problem was the race conditions
that we hopefully already eliminated. I got an out of memory
error running the samples tests in Eclipse, but then it went
away again (something to look out for).

[Fixes #54925992] [bs-280]
Fix README.md typo
Startup time for CLI app much quicker now

The Boot resolver didn't transfer enough of the settings
of the default ChainResolver. Adding a boolean flag was
enough to make the chatter die down for dependencies
that were unneeded.
