[QScintilla] some Lithuanian characters cannot be input by keyboard

[Yuya Nishihara]

Hi,

I received the following bug report from a TortoiseHg user.

> Commit message input does not permit to input a "į" Lithuanian character,
> in TortoiseHg v2.10.1 it was treated as backspace...

It is probably because the key code for "į" conflicts with SCK_LEFT or
SCK_RIGHT.  When the "į" key, which is "5" in US keyboard, is pressed,
event.key() returns 302 on Qt 4.8.4 and 303 on Qt 4.8.5 [1].

I guess the problem can be avoided by the following change, but there might
be a side effect.

diff --git a/Qt4Qt5/qsciscintillabase.cpp b/Qt4Qt5/qsciscintillabase.cpp
