That class does not provide any sriptable signal

TODO: it is really better to move those dbus interfaces up into class
MainWinow, which is more natural accroding to the '/Windows/N' naming
schema

That per-color transparency looks like a heritage of the pesudo
transparency in the KDE3 era. It is basically not used in current code.

The intention of the code is fine: when konsole is just started, do not
show the size hint since it could be boring and confusing. However, the
code just doesn't work, and using a static variable is definitely a
mistake here.

Apparently I didn't take a close look at the implementation detail of
memory-based history when I added the 'isRealCharacter' flag. That
missing information causes some wrong behaviors randomly when using
memory-based history.

An internal property is introduced to record the untranslated name.
When saving profile into disk, always refer to that untranslated name
to get the filename.

This extra consideration is intended to deal with the situation when the
profile's contents are i18nized. The typical example is the "Shell" profile
shipped by default.

_bellMasked is mistakenly set as true initially, which make it stay as
true forever. So bell never happens .
