Couldn't delete files in module documents and files anymore

[MightyMCoder]

After applying #1736 it is not longer possible to delete files in "documents and files" (see Forum Post 35754).

Problem:

The HtmlTable in "documents and files" is created with '-' in the ID:
$page = new ModuleDocumentsFiles('admidio-documents-files', $headline);

Possible fixes:

1. replace all '-' with '_' in all HtmlTable creations.
2. replace all '-' with '_' in HtmlDataTable.php before adding the ID to the JavaScript constant declaration.

@Fasse: What is your preferred fix? What do you think?

[Fasse]

Replace all - with _ in all HtmlTable creations would be a good idea because in Admidio 5 this is the default syntax for ids.

[Fasse]

Also in Admidio 5 most IDs should have a prefix adm_

This must also be fixed in the master.

also added to master fix: '-' in Html(Data)Table Ids prevent using modal windows
