[ww-tedit-dev] scan function names for .c files

[petar marinov]

Today I completed the function that scans for function names in .c 
files. it worked out nicely combined with some modifications in the 
syntax highlighting code.

from the syntax highlighting function:
-- I get all the comment areas marked;
-- I have all all the operators marked, this makes '{}' and '()' easier 
to pick;
-- I have all lines that contain no {} characters a marked as such and 
not scanned;
-- I have the current {} nested level;

Matching parenthesis usually involves scanning a line or a few lines and 
is thus not very expensive.

Matching curly braces involves more of a scanning, for this the syntax 
highlighting keeps tab of the current nested level at the end of every 
line. This allowes for very fast calculation of the current nested level 
anywhere in a single line based on the value at the end of the previous 
line.

I will now work to produce output for the bookmarks manager and add new 
bookmarks filter to show the functions in a file.
