Eze and E-hentai plugin source URL's are not compatible

[LoLsAlEd]

Hello, I have found a issue with the way the eze plugin stores the source URL which makes it not compatible with the e-hentai metadata plugin.

LRR Version and OS
LANraragi: v.0.8.4
OS: DSM 7 (Synology)
Install: Docker

Bug Details
If you import metadata using the Eze plugin it adds the source from the info.json to the gallery. But if we want to update the metadata using the e-hentai plugin it will not recognize the existing source tag and will attempt to search for a matching a gallery.

It looks like the issue is caused by the Eze plugin adding a space between Source: and the URL. This results in the regex not matching the existing source.

Eze Plugin:
source: e-hentai.org/g/2156186/b644822831

E-hentai Plugin:
source:e-hentai.org/g/2156186/b644822831

To resolve this issue I think the regex to detect a existing URL in the e-hentai plugin needs to be updated to handle the space, that is included from the Eze plugin. For example:

/.*source:\s?e(?:x|-)hentai\.org\/g\/([0-9]*)\/([0-z]*)\/*.*/gi

Please let me know if you need a sample file.

The issue mostly comes from the Eze plugin incorrectly adding a space to its source: tags, but I've gone ahead and also improved the regex on the EH side so that existing tags with a space in them work properly.

Let me know if there are any other issues!
