fixes #39

After further considering PR #21's arguments, the setup script should
not go around setting `color.ui`:

* it shouldn't be needed for recent gits with default compile

* it may override advanced users's own colour configuration/
  customisations (or disabling)
* it forces default colours on users for which it may be useless
  (colour- blind) or even detrimental (other vision impairments)
* some linux distributions apparently default to idiotic pagers which
  can't handle ANSI colour codes by default and spew garbage to the
  terminal

[ADD] convert bzrignore to gitignore

* don't set globally
* set for ui, not each command individually

[IMP] Move migration instructions on top, remove cruft

Prompts don't work with curl | sh as the stdin gets filled with the nothing out of curl

redirections by default, so use the correct URL

creating CI-conflicted situations is really annoying, not doing that would be great

Basic git doc for employees

* replaced sphinx :guilabel: directive by a simple strong
* moved rendered notes to non-rendered comments, not that I expect anybody to
  care or help /emo
* remove an explicit code-block directive by a simple ::

  subscriptions setup and events generation during create and write operations
* added import option to optionally set up that context key and speed up
