Test Case 1-11: Does not accept names with periods

[mararufino]

I used the last name 'Sta. Maria', but system did not accept it:

Same with first names. I used 'Ma. Andrea' (Ma., short for Maria, is valid because it is actually indicated in my own birth certificate that my first name is 'Ma. Andrea')

[yosefconsolacion]

fixed: string regex now supports periods.
