Update semantic shortcuts

Update BKeymap::GetModifiedCharacters() to translate a given character
and set of modifiers filling out a list of all characters that match for another
set of modifiers.

This allows us to, for example, get all characters in the normal map that
have the '+' character in the corresponding shift map.

It is fully generic allowing one to get a list of characters in any map given
a character and modifiers of another map.

Also I converted from using a BList to using a BObjectList.

With this, along with BWindow::HasShortcut(), the semantic shortcuts now
work not only with Command+'=', but any key in the normal map that has
'+' in it's shift map as long as it isn't already taken by another shortcut.

Keymap: Add a method to get modified characters for a key

This method fills out the passed-in BList of modified utf-8 characters for
a given utf-8 character and set of modifiers.

For example if you pass in "=" and B_SHIFT_KEY the list will get filled
out with each character in the shift map that has "=" in the normal map.

Each supported keymap modifier combination is available.

The reason this is useful will soon become apparent.

A BList is used because the character might be mapped multiple times,
for example if you have a Mac keyboard you've got two "=" keys, one in
0x1d and one in 0x6a.

The caller is responsible for creating the BList and destroying it as well as
freeing the resulting character strings.

* The Keymap::IsDeadKey() of the Keymap preferences which was the main source
of BKeymap was not compatible with IsDeadKey() of the other Keymap
incarnations.
* Now, I've renamed IsDeadKey() to DeadKey(), and introduced a new
ActiveDeadKey() method that works like the other former IsDeadKey().
* This fixes the dead key problems my earlier BKeymap work introduced.

* Factored out a single base class out of the three Keymap implementations we
had in our tree.
* Adapted Keymap, <input>keyboard, and consoled to use it - the additional
functionality is implemented via a subclass in the first two cases.
* "keymap" will come next.
