Generate:Migration Accepts "int" field type

[redknitin]

When creating a migration using the Laravel 4 Generators, no validation error is displayed when using "int" instead of "integer".

Example
This should cause a validation error:

php artisan generate:migration create_emp_table --fields="name:string, dept_no:int"

This should pass validation:

php artisan generate:migration create_emp_table --fields="name:string, dept_no:integer"

Currently, because the "int" is accepted, the migration file is generated but on executing the migration with the command php artisan migrate, the migration fails with a:

{"error":{"type":"Symfony\Component\Debug\Exception\FatalErrorException","me
ssage":"Call to undefined method Illuminate\Database\Schema\Blueprint::int()"
,"file":"C:\xampp\htdocs\darkangelofdemos\app\database\migrations\2014_09_29_090
445_create_emp_table.php","line":19}}

I've seen the issue reported in the title of #225, but the original message seems to have been blanked out and the issue closed.
