improved commends in env file. inline commends now work.

[Karl1b]

now inline commends can be used by space and #

will work
API_KEY=thisisanapikey # This is a commend

will work
API_KEY=thisisanapikey #This is a commend

will not work (no space before #)
API_KEY=thisisanapikey# this is a commend

I like this @Karl1b. I suppose if we wanted to be REALLY thorough we could also allow escaped values for # like "This is a value that ends with #". But the case where somebody has a value that ends with " #" is probably so few and far between we don't need to worry about it.
