[Multi] Minor improvements for my bridges

[ORelio]

Hi,

Here are a few improvements for the bridges I am maintaining:

• Anidex: Use alternate domain name to circumvent ddos-guard
• Dark Reading: Hide dummy articles without content
• FuturaSciences: Fix content extraction, strip inline scripts from content
• GBAtemp: Fix content extraction in Tutorials mode
• LeMondeInformatique: Remove encoding conversion
• NextInpact: Fix article subtitle extraction
• Releases3DS: Allow monitoring Nintendo Switch releases as well
• TheHackerNews: Fix article author containing an invalid character

Also two minor fixes to the RSS-Bridge core:

• FeedExpander: Fix PHP notice on empty uri field
• Markdown: Fix images with empty alternative text

Changes are minor so I grouped them into a single Pull request. Hope you don't mind.

EDIT: As requested by @em92 in #1692, changes for Anidex and Releases3DS were removed from this PR.
EDIT: Also removed changes for NextInpact as the bridge is being reworked (#1692)

The rest LGTM.

Just added one more commit for AnimeUltime, similar to LeMondeInformatique:

• AnimeUltime: Remove encoding conversion

@somini Any issue with this PR? "The rest" suggests something may be missing in your message.

I meant besides the other comments I did.

Thanks @somini, I could not see your comments until your last reply. I'll address them.

As requested by @em92 in #1692, changes for Anidex and Releases3DS were moved to #1693 and #1694, respectively.

TheHackerNews - ok
Next Inpact - related #1692. Waiting for new version
LeMondeInformatique - ok
GBATemp - ok
FuturaScince - ok
AnimeUltime - ok
Darkreading - didn't find those dummy articles, but ok

FeedExpander and Markdown fixes - ok

I would merge this PR immediately if it didn't have Next Inpact commit. I suggest to take it external PR

Thanks for your time in reviewing my pull requests 👍
Indeed, the NextInpact commit is not needed anymore as the bridge is being reworked. Removed it from the PR.
The Darkreading dummy articles are empty articles with only a title, they were polluting my feed reader a few months ago but maybe they stopped putting them in their RSS feed? Anyway, I think it does not hurt to keep the check for empty content, just in case.

Thanks @ORelio !
