Improve globals resolving, object key completion and description #50
Description
Currently, only global definitions references are picked up, but it would be nice that their values are also displayed instead of "global variable".
Also, if some variable is object so it has nested values, it would be nice to have completion for those values (in this case I would expect to see value_1 and value_2 as primary completion values).
