#23 Greek letters and some 'missing' features

As for \infty symbol, I found some troubles with greek letters.

* omicron is not passed correctly
* cap letter Lambda is missing
* In some format files I found 'lamda' i.o. 'lambda'

--------------------------------------------------

In the first tab (symbols), it would be nice if you could add the \emptyset symbol

In third tab (grouping), \floor and \ceil symbols and the norm symbol (||___||)could be useful (and maybe non-matching curly-braces could be added; I mean \left\{___\right. and \left.___ \right\})

In the greek letters tab, besides omicron and Lambda bugs to be corrected, you could add the var-greek letters (\vareps \varphi and so on)
