Without this commit, all marks are displayed in the target show page,
even the marks not related to the current target. This function should
fix this issue.

Note that the filter should be done in SQL for simplicity purpose in a
near future.

This helps readability in the code.

The left thumb was wrongly associated with the fpc 14 (left four fingers
taken simultaneously).

This is a temporary patch, to allows the import of the modules for
documentation purpose.

This will improve the workflow for the admin users while creating the
AFIS targets. If not existing, the target folder will be created
(empty). The user will be redirected to the target display page.

At the moment, this feature will only show a question mark for segments
without a target folder defined; the question mark will not be displayed
if the admin created target but did not upload an annotation (i.e. not
fully configured the target). This shall be patched on a future commit
to check for the presence of a annotation image.

The buttons should now be the correct size in regards of the outer div,
even when the page is resized.

Before, for some page size, when there was just not enough space for one
button more, the outer div was shrunk, but the button was not, hence
producing an overflow of the button, which was not nice to see.

In the 'utils' module, the imports are relative to the current file; the
variables can not be named like an other module (here the variable 'sql'
was conflicting with the module 'sql').

If not present, the default is assumed to be "touching" and "none"
