Fixed name generation bug (issue #26)

[fsgreco]

This PR will fix this issue #26

In doing so I also tried to standardize a little the component naming convention into PascalCase (either for the name of the file and the folder as well as the name of the function that it generates).

e.g this commands now will work without errors:

new-component a-component-with-hyphens # results in AComponentWithHyphens (folder,file and function name)
new-component a_component_with_underscores # results in AComponentWithUnderscores
new-component aCamelCaseComponent # results in ACamelCaseComponent
new-component "a component with spaces" # results in AComponentWithSpaces
