Writing style guide doesn't match company writing style guide

[GuySartorelli]

The writing style guide for Silverstripe CMS docs doesn't include everything from the company style guide in confluence.
There is a chance there are conflicts between the two, as well.

To decide

• To what extent do the docs need to follow the company style guide?
  • Take into account that the company style guide has changed and may change again outside of our control
    • keeping the docs up to date with those changes may be difficult
    • We ideally don't want to update the style guide for new docs, which then end up reading completely different from existing docs.

As much as everyone appreciates the company's contribution to the project I think certain things could/should be independent and it should be the OS CMS hat to wear first ;-)

I 10000% agree. This card came about because of #472 which says to use the company style guide.

#302 is bringing some parity between the two - I think we can all agree to put this to rest once that's finished and merged, and just use the publicly documented style guide henceforth.
