Kernel: Fix some race conditions in TCP stack
...
Remove race condition if two acks are to be sent one after another.
Always unblock semaphore once TCP thread has done something. This
allows better chance of TCP sending to succeed.
There are multiple places in the networking code that would require
thread-safe entering to blocking mode. I should add some API for this
so that a lot of race conditions could be removed.

Kernel: Fix E1000 interrupt handling condition
...
I had written the ICR register check backwards which lead to interrupt
handling only when it was not needed, and no handling when it was
needed. This somehow still worked, just much slower often requiring tcp
resends from the server.

General: Add simple contribution guide lines
...
README now contains simple contribution guide lines that should be
followed. I am now more open for public contributions to the repo
if people are interested.
Create a discord server and link it to the README. Discord seems to be
a nice platform for general messaging.
