Added ENotifyKeypresses and ECaptureCtrlC flags to CCommandBase.
Commands can now get keypresses and handle ctrl-C via callbacks instead of having to implement custom active objects. As part of this extended the CCommandBase extension interface to MCommandExtensionsV2 for the new virtual functions KeyPressed(TUint aKeyCode, TUint aModifiers) and CtrlCPressed(). sudo now cleans up correctly by using ECaptureCtrlC.

==name echo
==short-description
Print a text string to C<stdout>. If no text is specified as an argument, reads from C<stdin> and writes the result to C<stdout>.
==long-description
Note, this command used to interpret escape sequences such as C<^r> and C<^t> itself. This functionality has now been moved into C<CCommandBase> so all fshell commands can benefit from it. A consequence of this change is that it is no longer necessary to double escape such sequences.
==argument string string optional last
The text to be printed.
==option bool e stderr
Print to C<stderr> rather than C<stdout>.
==option bool w wrap
Wraps the text to the screen width, ensuring that words do not get split across lines.
==option uint i indent
The number of characters to indent the text by. Only has an effect when used with C<--wrap>.
==option enum a attributes multiple
The attributes to assign to the text written to the console.
==enum-value bold
==enum-value underscore
==enum-value blink
==enum-value inverse
==enum-value conceal
==option enum f foreground-color
The color the font glyphs are to be drawn in.
==enum-value black
==enum-value red
==enum-value green
==enum-value yellow
==enum-value blue
==enum-value magenta
==enum-value cyan
==enum-value white
==option enum b background-color
The color the rectangle behind the font glyphs is to be drawn in.
==enum-value black
==enum-value red
==enum-value green
==enum-value yellow
==enum-value blue
==enum-value magenta
==enum-value cyan
==enum-value white
==option bool B binary
Write to the console in I<binary mode>. Note, not all consoles support the notion of I<binary mode>. If not, KErrNotSupported (-5) will be returned. In practice, currently only the VT100 console variants support this.
==option bool n no-newline
By default echo will append a new line (C<CRLF>) on to the end of the C<string> argument, if it doesn't already have one. Use C<--no-newline> to prevent this.
