CLI framework should support alternative option formats

[Andrew Nicols]

At present the CLI framework grabs $argv wholesale and works through it testing whole words.

Typically, the short form of an option has always allowed a slightly different form. Whilst the long option might be
  --foo=bar
The short option should support:
  -f bar

Additionally, both options should support the use of quotes:
  --title="Hello World"
  - "Hello World"

We therefore need to implode the $argv array, and write a suitable regexp to handle this in a while loop instead
