"/" character in sequence name should not be allowed

[Jeanfi]

In v1.11 #41

When using the "/" character in sequence name, (example : LRGB 60s-90s \ 76g 15o) when saving the sequence or adding as template an error is raised and log reports :

[2021-01-30T19:26:50.4716] [ERROR] [Message] Could not find a part of the path 'C:\Users\Astro\Documents\N.I.N.A\Templates\LRGB 60s-90s \ 76g 15o.template.json'. at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)

"/" character should be forbidden when user is typing the name of the sequence or at least a message should tell the user to modify the name of the sequence when saving.

For the next nightly build, the invalid filename characters will be replaced on saving. The name can still support these characters, but the filename will replace them.
