Support the use of space in file names instead of the UriEncoded format

[kolgepratik]

Currently, if i have to mock a request with query parameter value that includes a space, i have to create the mock file something like this:

GET hello/ getMockedResponse--api=Hello%20World.mock

What would be great is if we can use literal 'space' instead, like

GET hello/ getMockedResponse--api=Hello World.mock
