Changed all *.* GUI file selection wildcards to *.

Created a file selection wildcard for use in the GUI for selecting peak lists.

This is used in the four user functions which read peak lists.

Shifted all wildcards used in GUI file selection dialogs into the new user_functions.wildcard module.

These have now all been standardised, and expanded to include more capitalisation combinations and
to include more *.* options.

Fix for bug #22105 (https://gna.org/bugs/?22105).

This is the failure spectrum.read_intensities GUI user function whereby a file name is turned into
lists of characters. A few changes were made to allow the Selector_file_multiple GUI element to
operate correctly.

Created the User_functions.test_spectrum_read_intensities GUI test to catch bug #22105.

This is reported at https://gna.org/bugs/?22105.

The problem is that a single file name is split up into many files when the file selection button
is clicked, one for each character of the file name.

Bug fix for the lib.arg_check.is_float_object() function.

The dim argument can sometimes be an integer rather than a tuple, but this was not handled by the
function. Now integer dim arguments are pre-converted to lists before performing all the checks.
