Quick And Little Personal Database

chdir() is now used instead of the path_file array to memorize files in a selected directory. The stdin buffer is now freed before an fgets() call.

At startup, the program now searches for correspondences between the
current date and the entries in the todo list.

All functions needed by the notebook support have been fixed. A function to sort the todo list has been added.

The insert() and delete() functions were changed
in order to add and delete entries easily and
quickly. The database for the expenses should now
be stable. The new functions for the array of
structures "notebook" need to be freed from some
bugs.

A save() function was split out of the main()
function. Some small bugs were corrected, such as
the ones in the show() and in the load()
functions. Now, while the program is running, you
can close one file and use the new empty pointer
for another file. The functions were rearranged
into two files, func.c and files.c, in order to
manage them better.
