Found a bug that if a / is part of the environment to delete it will not be removed from the environment list.
Found a bug where if someone autocompletes the deletion of an environment it was not being removed from the list due to the trailing / so reworked method that removes an environment from the environment list so it can handle autocompleted file paths as well as manually typed.
corrected some DocBlocks with incorrect throw classes.
Updated to PSR-2 standard on entire project.
Converted any remaining tabs to spaces; moved all concatenation '.' to the end of the line instead of the beginning.
Updated all double quotes not used for interpolation to single quotes.
fixed create command file
Updated the concatenation to lead with the operator.
Merge pull request #30 from pddevins/PSR-2-review-complete

PSR-2 review complete
Merge remote-tracking branch 'upstream/master'
Created an object for reading and manipulating the environments.json file that we can migrate current functionality into.
Added in an instantiation of the new environmentFile object and set class for interface with that object.
Updated creation to now install environments in the ~/.virtphp/env folder by default instead of current directory.
Changed the $_SERVER[home] method for getting the home directory to one used throughout the rest of the code.
Added a check that the env to be deleted exists and then set path to one tracked in the environments.json file.
Cleaned up some PSR stuff.
Replaced specific referent to forward slash with directory separator to make it more cross OS.
Added in a check that prevents the same environment name from being used twice.
Merge branch 'master' into localized-install
Removed the construct as it was breaking all tests and just added the check in the get method.
