Fix 'iDate' add and sub

v2.0.0 Changing to new specifier `i`

What is new?

Because of Using 'h' specifier might cause overlap with hour's specifier. The specifier has been changed from h to i as a prefix. So for example in the previous version to get the four digit year we use hYYYY. In version 2.0 or above you should replace it with iYYYY and so on.

v0.4.2

What is new?

• Update moment version to 2.9.0 .
• Feat(hMonth): add support to month name.
• Using lang() method instead of localeData() to use the same what is used in moment.js itself.

0.3.4

Remove node vserion 0.8 from  .travis.yml
