About Bitcoin HD-Wallets' derivation path notation scheme (BIP32, BIP44)

Hi there,
I'm having trouble to fully understand the derivation path notation, for example ( https://github.com/bitcoin/bips/blob/mastebip-0044.mediawiki ):
m / 44' / 0' / 0' / 0 / 0
I have 3 primary questions:
  1. What do the ticks (apostrophes) mean? Where does this notation come from, is it common in cryptography?
  2. What is an account? (Intended business use case)
  3. Lets say I only have coins on the first and second address, when I spend the second address, where is the standardized way to put the change, first or second change address?
Looking forward to help. Thanks!

Are all possible BIP39 mnemonic seeds produce a valid BIP32 master private key, which produce valid Bitcoin private keys?

The question is provoked by the fact that not all 256-bit numbers are valid private keys. To be valid it must be from 0x1 to 0xFFFF FFFF FFFF FFFF FFFF FFFF FFFF FFFE BAAE DCE6 AF48 A03B BFD2 5E8C D036 4140.
Is it possible that some randomly chosen (with dice, for example) mnemonic seed is not valid, because it produces not valid private keys? Is there a protection for this?
I know that Electrum can be configured to accept a random list of words (user-generated) and to ignore the incorrect checksum.
What is the risk something to go wrong by using manually selected words (selected with dice and "Bip39-diceware" for example)?
Edit: I looked through the documentation (BIP32) briefly and looks like I found the answer:
In case parse256(IL) ≥ n or ki = 0, the resulting key is invalid, and one should proceed with the next value for i. (Note: this has probability lower than 1 in 2127.)
So, it looks like there is a protection envisioned by the developers. Whew.
Edit 2: Actually, no.
In practice, this will never happen (the probability is so small we can ignore it), and likely implementations don't even bother checking the condition.
This is scary.
Edit 3: I tested Electrum. See "I successfully imported invalid Bitcoin private key! #5797" on the Github page.
Edit 4: It's not a bug, it's a feature.
SomberNight said on Github:
Effectively, with what we are doing, some group elements have two representations; while most only have one. Your "invalid" key contains a number that is too large to be a group element; but we subtract the group order from it and use that number instead. It's as if you imported the "valid" key in the first place. In fact if you try to export it, we will give you the "valid" one.

Can I import my own BIP32 wallet into Bitcoin Core?

Let's say that I've created my own BIP32 extended private and public key. Can import these (or only the extended public key in order to create a watch only wallet) into Bitcoin Core? I understand that Bitcoin Core now uses BIP32 behind the scenes to generate new addresses. Or am I forced to only using HD wallets created in Bitcoin Core, alternatively importing separate private keys?

The Bitcoin reference client uses randomly generated keys. In order to avoid the necessity for a backup after every transaction, (by default) 100 keys are cached in a pool of reserve keys.
