doc: Re-organize and improve Java Interface documentation.
* doc/interpreter/java.txi: Add usejava, isjava functions, debug_java,
java_matrix_autoconversion, java_unsigned_autoconversion to docs.
Re-organize to put functions in logical order. Add new "Dialog Box Functions"
node.
* doc/interpreter/system.txi: Remove usejava from list of system functions.
* libinterp/octave-value/ov-java.cc(FjavaObject, FjavaMethod,
Fjava_unsigned_autoconversion): Improve docstrings.
* scripts/java/javaArray.m: Tweak docstring.
* scripts/java/listdlg.m: Wrap long lines in docstring. Improve
