crecord: stop raising error.Abort if curses is not found (issue5008)

On some servers, python curses support is disabled. This patch not only fixes
that but provides a fallback on other machines (e.g. Windows) when curses is
not found.

The previous code was actually flawed logic and relied on wcurses throwing an
ImportError which demandimport wouldn't throw. So, this patch also fixes that
problem.

# An example WSGI for use with mod_wsgi, edit as necessary
# See https://mercurial-scm.org/wiki/modwsgi for more information

# Path to repo or hgweb config to serve (see 'hg help hgweb')
config = "/path/to/repo/or/config"

# Uncomment and adjust if Mercurial is not installed system-wide
# (consult "installed modules" path from 'hg debuginstall'):
#import sys; sys.path.insert(0, "/path/to/python/lib")

# Uncomment to send python tracebacks to the browser if an error occurs:
#import cgitb; cgitb.enable()

# enable demandloading to reduce startup time
