The new CentOS 7 beta lists the distribution as "CentOS Linux", which
breaks the distribution detection and class loading. This patch fixes
that by taking just the first entry in the string when a space is
detected.

Allow gem executable to contain spaces

Virtualenv's activate script sets the VIRTUAL_ENV environment variable to the path of the virtualenv. Checking this variable is a reasonably common way to verify that execution is happening in a virtualenv. It would be convenient if this module's virtualenv handling set this environment variable.

Allow npm executable to contain spaces

rbenv has a special exec function which loads the correct ruby version before executing a command.
The syntax for this is `/usr/local/rbenv/bin/rbenv exec gem ...` for example.
But previously when specifying executable='/usr/local/rbenv/bin/rbenv exec gem' this would not work because the string was treated as one executable. This PR fixes that by splitting the executable on spaces.

NVM has a special script which loads the correct node version before executing a command.
The syntax for this is `/usr/local/nvm/nvm-exec ...`, so `nvm-exec npm list --json` for example.
But previously when specifying `executable='/usr/local/nvm/nvm-exec nvm'` this would not work because the string was treated as one executable.
