modification in styles admin

[singulae]

I made a modification (very little) in general buttons to cancel, delete and view of the administration area. They now have rounded edges, like other elements ..
It is a small contribution ..
Do not know if this is the right place to say ... I hope that is correct.

The changes are as follows:

Replace X by × in:
admin/archive.php -> line 79
admin/components.php -> line 102
admin/backups.php -> line 79
admin/upload.php -> line 234
admin/template/js/jquery.getsimple.js -> line 122
admin/inc/template_functions.php -> line 924

Replace # by '.strip_tags(strtolower(i18n_r('VIEW'))).' in:
admin/inc/template_functions.php -> line 921


And change style.php by posted file: (is better to change the file than change line by line)

(see screeshot in .zip)

you prove it and tell me your opinion?

thanks
