SVN commit 1014360 by darioandres:

- Reverting the last change to use CSS to global formatting, as it has major
problems:
  - All the text is saved as html and that includes the proper formatting as
html/css; so
  setting a global CSS style will not affect future changes. ("local css" >
"global css" in priority)
  - It also conflicts with the way KRichTextEdit works

- Set all the font changes using the KTextEdit "set*()" methods, but previously
selecting all the text
  using QTextCursor (and then restoring the old cursor (restore text
selection))

- On updateTextGeometry(), only the font family and size changes are applied.
This are non-destructive changes
  as the user has no other way to set this settings beside using the
Configuration Dialog; so we can do them
  at any time

- Bold and italic settings are destructive (as setting a global bold/italic
will override the custom
  formatting the user could have done when manually changing them using the
Notes controls at the bottom)
  - So, we are going to apply this destructive global changes only if needed
(if any of them changed in the
  configuration dialog)

- Small fix on load: Do not load the font properties on the Configuration
Dialog as the font() property
  of the textedit. This is not true, we should use our stored var "m_font"
which properly loads the settings
  from the config file
