#9 Add hooks to basic actions and writable area in status bar

[Anonymous]

It would be very useful to be able to call definable python
functions when certain actions occur. For example:

File is opened.
File is Closed.
New buffer is selected (tab clicked).

createCommand(<python func>, <command>)
addHook(<hook type>, <command>)
delHook(<hook type>, <command>)

There could be more than one command assigned to each
hook.

This could be combined with a python writable area in the
status bar (next to where the line and col are displayed) to
give interesting information about the currently displayed file.
E.g. Read only file, CVS version, file size, number of lines...

The python API will be much extented in the future. Hooks
will be added too.
