Trimming the input of whitespaces

[mukkachaitanya]

Description

The inputs of the inquirer have not trimmed off the white spaces and are considered a part of the input.

Steps to Reproduce

Login using the autolabjs init command for a user say testuser:

1. Login using username testuser ; logs in.
2. Login using username testuser ; fails.

Expected behavior: The login must go thorugh by trimming off the whitespaces

Actual behavior: Outputs Invalid Username or Password.

@mukkachaitanya Good catch, but this is not a high priority at this point. Please let this issue simmer a bit and focus on other high priority points from the refactoring page.
