# Function add_require()
# Adds a require line to a js file, if line does not already exist.
# It first scans the 'file' for 'search' arg. If 'search' is not found,
# it replaces 'where' arg by 'replace' arg.
#
# ARGUMENTS:
#   $1: search = line(s) to add, to check if it already exists
#   $2: where = where to put it ?
#   $3: replace = where "+" search
#   $4: file
#
# OUTPUTS:
#   Some echos of the progress of the script
