Check cite-Name for existence not for spelling

[GoogleCodeExporter]

> What steps will reproduce the problem?
> What is the expected output?
When I write \cite{foobar2002} the spellchecker is checking the spell of 
"foobar2002" as this is mostly some kind of shortening etc. it's mostly marked 
red.

> What do you see instead?

I would like him to check if the given reference does exist, and if not marked 
with an other color (blue for example).

> Please provide any additional information below.

- Should be easy to integrate, since you already have the list of existing 
cititations
- Lesser false positive red means more clearer text.

• Added labels: Type-Enhancement
• Removed labels: Type-Defect

Same is valid for other cite commands like \citet and \citep and the cite 
commands used with biblatex, like \footnoptecite \parencite \autocute and so on.

Additionally, the situation is similar for
\includgraphics[]{nospellcheckrequired}
and
\label{fig:nocheck}

This is a great suggestion, it would really help out when using the main spell 
check feature if we could ignore all the labels, citations, etc.  

Perhaps a nice implementation would just allow ignoring regex matches.  Then 
you could include by default a set of regex matches for \label{XX}, \cite{XX}, 
\citep{XX}, etc.  This way if a user writes a whole bunch of their own macros 
that they don't want spell-checked, they could add their own regex.

Sorry for adding another quick comment, but I thought of a few more:
\ref{XX}, \eqref{XX}, maybe \begin{XX} and \end{XX}

The spell checker marks almost all citations \cite{xy} and references 
\ref{fig:myFig} as mistakes. This means that actually using the spell checker 
to check a report is almost impossible.

I believe the default should be for the spell checker to ignore the contents of 
{ } by default, perhaps with a couple of exceptions like \footnote{ } and 
\section{ } for example.

It is common to localize formatting and other effects by putting curly braces 
around text, including whole paragraphs, so I think comment #7 might be a bit 
too broad.

Improved spell checking capabilities would be great! In every other regard, 
TexMaker is awesome!
