Complete with templates, other fixes

[NexiusTailer]

1. Convert <TipNPCCallbacks /> into <NoteNPCCallbacks />: now all template boxes noticing that 'something' is callable by NPC displays with the right label on their box (that's always note, not tip), in all localizations too
2. Remove <LowercaseNote /> template component and all manually written warning boxes about 'something' must start with lowercase letter: that was a thing for SA-MP wiki where there was some tech limits in their wiki engine which couldn't make articles starting from lowercase letters, so such warning was a necessity there. Looking even at the UG-MP wiki, which is also was based on SA-MP wiki but uses different engine to display articles, it dropped such a warning completely from every page (let's take random native as an example)
3. This commit previously removed non-existent NPC callbacks from the English docs, but didn't make it for the rest of translations which already took and translated this stuff. This PR removed all these leftovers from every translation too
4. Some translated articles stated samp server bugs without a note that it was fixed in omp server. I scanned all those marks in English translation, compared with the translations where there was such an already made translated "fixed in open.mp" clause at least once and applied to every other mentioned bug inside that translation. I.e. I ported this important note into those translations which already had this translated text somewhere, without inventing or auto-translating anything by myself. Since this clause were always at the end of the whole sentence (even after the final dot), no possibility for any mistakes here could be done while having now more relevant info between the translations
5. Removed a never implemented diskfree file native (wrongly added probably by mirroring Pawn 4 natives)
