This changes the semantics of isOK() and operator(), comments from Bernhard below:
With the old version of lyxlex it was _impossible_ to check whether reading an integer, float, ... succeeded or not. The current solution to check for is.bad() in some cases and in other cases use is.good() does not give the desired information. Moreover the result of is.bad() depends on the stl implementation and behaves different for linux and windows.
the bug was introduced by the patch that fixed the bug that crashed lyx when "inset-insert ert" was executed from the command buffer.
The lexer has the method isOK() which reflects the status of the stream is.
The operators void* and ! are not really well defined (they depend on the value of is.bad()). What is missing is a test if the last reading operation was successful and thus the returned value is valid.
That's what i implemented in this patch.
The new rule for using the lexer:
if you want to know if the lexer still has data to read (either from the stream or from the pushed token) then use "lex.isOK()".
If you want to test if the last reading operation was successful then use eg. "if (lex) {...}" or unsuccessful then use eg. "if (!lex) {...}"
an example:
int readParam(LyxLex &lex) {
int param = 1; // default value
if (lex.isOK()) { // the lexer has data to read
int p; // temporary variable
lex >> p;
if (lex) param = p; // only use the input if the reading operation was successful
}
return param;
}

Get rid of LyXRC::font_norm_type, since it is no longer needed for arabic

LyXRC::font_norm stays for now, since it is still used for the kbmap stuff.

Cleanup and polish of the Citation dialog:
- now simple citation insertion can be done with the keyboard only (enter key will close the dialog and insert the chosen key).
- now search also within bib entry information (very fast)
- new case sensitive option
- new regex option.
- QCitation: code simplified, some code went to ControlCitation.
- QCitationDialog: code simplified
- lots of polish in the dialogs...

(arabic_table2): Rename to arabic_table and update code points to UCS4.
The old code points in this table where a custom encoding:
Some ASCII positions and some unused positions of the iso8859-6
encoding where used to encode the shaped forms. Example:
The character hamza was encoded with 0x41. The iso8859-6 encoding in
lib/encodings contained ithe value 0xfe80 at position 0x41 before
the transition to unicode => Change the value 0x41 to 0xfe80 in the
table.
This old custom encoding was needed because the transformed characters
needed to be transported through 8bit characters.
