Using more than 6 letters results in "Error: Invalid ID"

[Zeklyn]

Hello! If you try to use more than 6 letters in the links/text tab it results in "Error: Invalid ID", do this with files and it'll result in a "Bad gateway 502" error. URLs are somehow capped at 6 letters.

Example

This is normal, as internally IDs are stored as 32 bits integers. However, the web UI should warn you and disable submission if the ID is invalid, which is visibly not happening. I'll look into it.

I also plan to rework most of the internal structure to remove that limitation as soon as I have more time.
