Support for TypeScript supporting version of knex migrate command

[ziyaddin]

Knex team has recently added TypeScript support for knex migrate command. knex-migrate will require update to support the new version of migrate command.

No knexfile at '/path/to/project/knexfile.js'
Please create one or bootstrap using 'knex init'

because of having knexfile.ts not knexfile.js

Also, migration files will likely be written in typescript as well

@ziyaddin @good-idea Mind giving a try with PR #47? It adds support for knexfile.ts lookup and generates Typescript compatible migration files.
