New Features: In Tab-View mode, Ctrl-number will take the user to
the numbered tab view. Modified files now show an '*' astrisk in
the view title. Debugger framework can now support PHP debugging.
Not important for python development, but at least that means the
debugger framework is more generalized.

# Purpose: - Instantiate datetime.datetime/date instance from a string
|
|
# date representation.
|
|
# Uses dateutil from http://labix.org/python-dateutil.
|
|
#
|
|
# - Creates string representation of datetime/date instance.

Optionally, a format string may be used. The format is only loosely

interpreted, its only purpose beeing to determine if the year is first

month. If no formatstr is passed in, dateutil tries its best to parse
|

the datestr. The default date format is YYYY-mm-dd HH:SS.
