L1VM - l1vmgodata links

Now the latest version of my l1vmgodata database has a new feature: you can add links between keys. And also remove them. You can get the links from the database from a key. This makes it possible to structure data beyond key/value pairs.

Here is an example:

Set link:

store data :water-n 'water'
OK
store data :water-chem 'H2O' 
OK
set-link :water-n 'water-chem'
OK

Get links total number:

get-links-number :water-n ''
1

Get link index 0:

get-link-name :water-n '0'
water-chem

Remove link:

rem-link :water-n 'water-chem'
OK

The L1VM l1vmgodata module was also updated with the new commands.
