Title set by dbus method setTitle() should be sticky by default

It is not intuitive and easy for users to find they need also
call dbus method setTabTitleFormat() to avoid that title being
replaced on session activity.

BUG: 262089
FIXED-IN: 4.8
Fix minor spelling issues.
Minor changes for consistency and better understanding.
Refine the description of what Ctrl+MidClick does in konsole
Make the description of --profile option consisitent with KDE4 konsole

The old description is clearly for KDE3 konsole.
Remove the description of the "Scroll Lock" feature

That feature seems gone in the KDE4 konsole. So remove it for
consistency.
Add "Did you know?" item for the featore of Ctrl+Wheel for zooming
Add explanation on how the -e option works in konsole.

Konsole treats all arguments after the -e option as one commnd
and runs it directly, instead of parsing it and dividing it into
sub-commands for execution. This is different from xterm.

CCBUG:170867
Add another common issue about running login shell in konsole

CCBUG: 54663
Minor change on code style
Move code around for better readability
Delete slot saveSession() which is not implemented and used
Simplify the code for updating codec action
Update _allControllers at the end of the constructor
Rename _closePerUser to _closePerUserRequest for clarity
Simplify the scrollback setting dialog to avoid potential confusion.

  - the change is not saved into profile and only influences current tab
  - remove the 'Save to current profile' checkbox
  - remove the 'Defaults' button
  - change dialog title from "Scrollback Options" to "Adjust Scrollback"
  - change action from "Scrollback Options..." to "Adjust Scrollback..."

The new dialog makes the "Adjust Scrollback..." action more consistent with most
of other actions in the context menu, since they only influence or work in the
context of current tab.

The UI change is not quite satisfactory. Feel free to refine the UI part
to make it more clear and elegant.
