The existing code had two issues: For one, e.g. calling a function that returned a null interface reference mapped that to JS null, while querying an object for a non-supported interface via `new css.uno.X...(y)` mapped that to an "empty" JS object instead. (So checking for a non-null reference needed to be done as either `x !=== null` or as `x.is()`, depending on context.) And for another, while calling $is() on a non-"empty" object worked fine, it failed on such an "empty" object (as the Embind internals of that object lacked the $$ property). So change the querying mechanism from the `new css.uno.X...(y)` constructor to a `css.uno.X....query(y)` function call syntax, which now returns JS null when querying for a non-supported interface. (And drop the broken $is method.)

LibreOffice API IDL Files Except UDK API
Contains all of the IDL files except those in udkapi.
i.e. the interfaces that are specific to the LibreOffice application. An artificial (?) separation.
The reference offapi/type_reference/offapi.idl and
udkapi/type_reference/udkapi.idl (formerly combined into a single
offapi/type_reference/types.rdb) are used to detect inadvertent incompatible
changes. They are plain-text .idl files (not strictly lexicographically sorted,
though, so they satisfy the .idl file requirements for no forward dependencies),
so in cases where we deliberately /do/ become incompatible they can be modified
manually.
Old such cases of deliberately becoming incompatible are listed in
offapi/type_reference/typelibrary_history.txt, newer such cases are recorded in
the git logs of (now superseded) offapi/type_reference/types.rdb,
offapi/type_reference/offapi.rdb, and udkapi/type_reference/udkapi.rdb, new such
cases are recorded in the git logs of offapi/type_reference/offapi.idl and
udkapi/type_reference/udkapi.idl.
