Added .hash() functions for vectors (#2043)

Browse Source 
* Added .hash() functions for vectors
* Update test to a non-zero sized vector
* Changed vector hash functions to hash the underlying bytes in a char slice, the same approch is used for arrays
* Added test for hashed
* Updated formatting to be consistant with C3 code style
* Formatting, use "self"
