Fix escaping/unescaping in wxLongStringProperty

Browse Source 
wxPropertyGrid::ExpandEscapeSequences() function should convert all valid
escape sequences (\r, \n, \t, \\) to the corresponding single characters
(CR, LF, TAB, backslash, accordingly) and
wxPropertyGrid::CreateEscapeSequences() function should do the reverse
operation and convert these raw characters to the corresponding escape

by backslash, the backslash is skipped.
Note also that depending on the system (port), some sequences of special
characters, like e.g. "\r\n", can be interpreted and presented in
a different way in the editor and therefore such sequences may not be
the same before and after the edition.
To display custom dialog on button press, you can subclass
wxLongStringProperty and implement OnButtonClick, like this:
