Adrien Bourmault 228df83a1a Merging from master (#34)
* Update Readme.md

* Debug this beautiful panicked kernel !

* Stuff I don't remember

* stuff

* merge

* merge

* Step 0 : InitTerms() is the bug

* Debug stuff

* Step 1 : StartPanic is the real problem

* Step 1 : StartPanic is the real problem

* Step 1 : StartPanic is the real problem

* Step 1 : In StartPanic is the real problem

* Step 1 : In StartPanic is the real problem

* Step 1 : In StartPanic is the real problem

* Step 1 : In StartPanic is the real problem

* Step 1 : In StartPanic is the real problem

* Step 1.5 : \n was a problem

* Step 2 : Well... It was a 'sleepy' problem

* Step 2 : Well... It was a 'sleepy' problem

* Step 2.1 : GetPanicStr is an array

* Step 2.2 : Now panic accept 8 chars

* Ok then !
