Fixed starting whitespaces detection

In vim, \s is for <Space> and <Tab>. Hence, we just want to
detect starting spaces.

This patch fixes the space detection by changing the regexp.

Update README with correct URL

The README give install instructions. The clone url was not correct
since my nickname starts with an Upper-case letter (Makohoek).

This patch updates the install instructions with the correct git url.

Fixup component polluting keyword higlighting

The regexp was too general. It also took into account the
keywords such as "component" or "domain".

This patch narrows the regexp a bit to avoid those erroneous
higlighting.
