[TASK] Handle sites without dimensions configured
[TASK] Use path access in EEL expressions

In order to work in protected eel contexts the EEL expression
for reading node properties should use path access instead of
calls to getter methods. This will allow the
TYPO3.TYPO3CR.Search to use the EelUtility from the EEL
package instead of own code.

Individual expressions for indexing should also be adapted to
use path access.
[BUGFIX] Trying to get property of non-object error

During indexing I got a 'Trying to get property of non-object' error
in the NodeIndexer on a line that contained invalid json (a truncated
error message). This change makes sure an error is logged if invalid
json is returned.

[FEATURE] Support greaterThan and lessThan for range filters

A range filter cannot be easily used in Eel expressions since the
TypoScript parser does not allow double nested curly braces for
now. The two new query builder methods expose a high-level interface
for doing that.
