PHPDoc Improvements (part 1)
Partial revert of 4c25e01fd7fa6b0f5539d33ee21b0e555abc5366

I was a bit careless with the sed scripts I used to cleanup the language
files, and removed some strings which I shouldn't have due to not doing
the match on whole words
Subprojects prevents load of manage_proj_edit_page.php

This is caused by type mismatch when calling check_checked which
compares a string to an integer. Solved by casting parameters to string.

Fixes #16473

This is to replace the use of ERROR_GENERIC when performing a strict
