EazyText : trunk updates

[Pratap Chakravarthy]

Hi all,

I have updated the trunk with couple of bug fixes and lots of
documentation updates.
You can track all the changes by looking at `bzr log` from r183 to
present (r197)

Apart from that I have also added a plugin to do syntax highlighting
for code blocks.
Just wrap the code block to be highlighted with wiki-extension syntax, like,

{{{ Code C
struct process {
struct process *next;
const char *name;
PT_THREAD((* thread)(struct pt *, process_event_t, process_data_t));
struct pt pt;
unsigned char state;
};
}}}

The trunk stays at 0.92dev.
Cheers,
Pratap
