Increase max string length of account properties

[Pytal]

Users may want to add longer text to some account property fields such as Biography/About. Currently the max length is 2048 characters, see below

server/lib/private/Accounts/AccountManager.php

Lines 197 to 199 in 4dc226e

	if (strlen($property->getValue()) > 2048) {
	if ($throwOnData) {
	throw new InvalidArgumentException();

We may either increase the max length for all properties or just for Biography, and if this is the case then we should decide on what this new max length should be :)

@Pytal this was not intended for longer texts and the limitation is, IIRC, a security/DoS prevention measure. If specific properties should be allowed to be longer there should be an exception for them, either by addressing the property name directly or a more abstract mechanism.

I'm fine with the length, although I don't like abitrary limitations (which is why talk chat messags are not limited).
But fine either way, we just need to properly handle too long input, and maybe show some counter when you are close to the limit like in file comments (limit is 1k I think and counter with remaining characters shows from 15 remaining(?) and gets red when negative)

This should maybe be shown in the capabilities?
So you can also have that as html max-length?

I would not do that to allow people to have longer text and reformulate it before submitting?

This has my vote :)

Very good point!
