Corercted galician translations gl.js

- Corrected "Octubro" --> "Outubro"
- Corrected "fai" --> "hai". "fai" is a spanized fail. Correct example: "two days ago" --> "hai dous días" (not "fai dous días")
- Corrected "uns segundo" --> "un segundo" (number agreement)
Update gl.js
Update gl.js

Corrected "un segundo" --> "uns segundos" (a few seconds).
I realised my error in last correction after take a look and correct gl.js in test section.

More fixes to Ukrainian: literary standard fix plus special case for 11 hours processing
added in a toISOString helper method to match the javascript date object's toISOString method
fixed missing space after function
aliasing the toISOString method to the toJSON method
The only solution I can propose with processHours function
Add duration.add() and duration.subtract() methods.
And this does work indeed, thanks to guru @ichernev
Add tests for duration.add and .remove
