Actually collection types are not harmonized to their interface
counterpart; this was implemented in the first proposal but wasn't
applied in the final review.

Fixes gh-2196

  Fix typo in howto.adoc

Closes gh-2199

The various servlet containers that we support vary in the quality
of their diagnostics when ServletContext.addListener fails. To make
problem diagnosis easier, this commit ensures that the toString of the
the listener that was being added is included in the exception that's
thrown when a failure occurs.

Closes gh-2197

Update template auto configurations to search for template folders in
the entire classpath rather than just the root jar.

Fixes gh-2184

Update GroovyTemplateAutoConfiguration so that the `/template`
folder check only occurs when the groovy-all jar is not being
used.

* thymleaf-conditional-comments:
  Auto-configure for Thymeleaf conditionalcomments

Add auto-configuration for thymeleaf-extras-conditionalcomments which
allows parsing of conditional comments for IE.

Example:

	<!--[if lt IE 8]>
		<link rel="stylesheet" th:href="@{/styleIE.css}"
		type="text/css"/>
	<![endif]-->

Without this dialect all Thymeleaf attributes are ignored inside the
comment.

  Clarify SSL "How-to" documentation

Update the SSL "How-to" documentation to make it clearer that SSL
configuration replaces the usual connector.

  Rename SecurityPrequisite -> SecurityPrerequisite

Closes gh-2179

Mixing Hibernate and a JTA provider may lead to duplicate JTA
dependencies as the API is published with different coordinates.

The following has been applied:

* We now use `javax.transaction:javax.transaction-api` everywhere.
* The `data-jpa` starter has been updated to replace the JBoss JTA
  dependency with the standard one.
* The `jta-bitronix` starter has been updated to use JTA 1.2 instead of
  JTA 1.1 (unfortunately, JTA 1.1 is published with different
  coordinates).
* The `jta-atomikos` starter has been updated to define a dependency on
  JTA as the current version does not do it at all.
* The HornetQ JMS server is also relying on JTA but that dependency
  should have been optional. It has been excluded for the time being as
  it was using (yet) another set of coordinates.

Update LoggingSystems so that they can reinitialize themselves
before logging begins. This allows reset of the root logger (which
may have been set to OFF in beforeInitialize) and also re-evaluation
of systems properties such as PID which may not have been set when
logging configuration was first loaded.

This commit may possibly reintroduce gh-1091, but it seems like
reloading is our only option.

Fixes gh-2125

Closes gh-2126

* pull2181:
  Remove duplicate "should" word from README

Ensure that the system temp directory is passed to the Jetty
WebAppContext. This prevents `jsp` folders from appearing in the current
directory.

Fixes gh-2169

Update DispatcherServletAutoConfiguration to alias a MultipartResolver
that is not named correctly. This allows the DispatcherServlet to pick
up any MultipartResolver bean, regardless of its name.

See gh-2162

The `joda-time-jsptags.jar` jar file cannot be skipped.
