v1.0.0: Merge pull request #3 from mrbabbs/bug/manage-birth-data

It is followed the resume-schema from jsonresume with the support of some custom sub-elements:

• keywords to each 'work', 'publication' and 'volunteer' item
• summary to each 'interests' and 'education' item
• location to each 'work', 'education' and 'volunteer' item
• birth to 'basics'

Date bug fixed.
