Creating Language Plugin not used for new language

[Roland Plüss]

Have been too happy too early. This Lexer generator is driving me
insane. It's claiming to use RegEx but it's not (what goes for [ ]
notation) which results in KDevelop constantly crashing left and right.
Culprit is a rather unhealty line of code generated:

    switch(lstate)
    {
    case 0:
        goto _fail; // no warning about unused label
_fail:
        {
            qDebug() << "error";
            exit(-1);
            lxFINISH
        }

... exit(-1) !!!

Whenever the generated lexer doesn't like one character in the parsed
file it right out kills the parent KDevelop instance without any warning!

You need to fix this as soon as possible since this could be the cause
for so many unexplainable kdevelop crashings.
