dockerfile improvements (#296)

Browse Source 
**Summary of changes:**

 - Added *some* inline documentation to make things a little more understandable
 - Replaced ARM toolchain dependency fetching, see #274 
 - Environment variable included to specify new or custom ARM toolchain. As ARM releases new versions of the toolchain, this URL can be changed.
