Generate eclipse project settings from gradle

Update gradle to generate the following project specific eclipse
settings:

- Java formatting
- Cleanup options
- Warning settings
- Code template with copyright header
- WTP module meta-data

In addition this commit changes the eclipse project .classpath file
to output test and main classes to different folders. This is required
to prevent eclipse WTP from packaging test classes into /WEB-INF/lib
jar files.

consider all methods when resolving properties. Methods are now
sorted such that non-bridge methods are considered before bridge
methods.

Polish author and copyright year

commit.

  isAnnotationInherited().

Allow 'gradle eclipse' without 'cleanEclipse'

Allow eclipse projects to be regenerated without first requiring the
'gradle cleanEclipse' task to be executed.
Fix eclipse .settings generation

Fix issues where gradle would not regenerate .settings files due to
the task being considered UP-TO-DATE.
Tweak eclipse warning settings

Hide raw-type, generic and resource leak warnings.
Improve exceptions for multi-operand expressions

Fix SpEL expression parser and tokenizer to provide better exceptions
when dealing with operations that expect two operands. For example,
prior to this commit the expression '/foo' would throw a NPE due
to missing operands to the left of '/'.

Issue: SPR-10146
SpEL support for static finals on interfaces

Update ReflectivePropertyAccessor to search for fields on super classes
and implemented interfaces.

Although the javadoc Class.getFields() implies that all public fields
of class should be returned SpelReproTests demonstrates that this is
not always the case.

Issue: SPR-10125
Prepend context/servlet path to FormTag action

The Form tag now fills in the context and servlet path if not present
