This prevents display of the warning for --dev and --olympic.

Added chain configuration options and write out during genesis database
insertion. If no "config" was found, nothing is written to the database.

Configurations are written on a per genesis base. This means
that any chain (which is identified by it's genesis hash) can have their
own chain settings.

The EVM is now initialised with an additional configured object that
allows you to turn on debugging options.

The debug package provides an RPC wrapper for glog settings and the
debugging facilities of the Go runtime. They can be triggered through
both command line flags and the IPC listener.

Also remove some duplication around address/index parsing.

Removed the legalese confirmation dialog. This closes #1992

* lines with leading space are ommitted from history
* exit processed even with whitespace around
* all whitespace lines (not only empty ones) are ignored

Changed the version number of geth to 1.2.0 so that dev builds are now properly build (instead of master). Note to self; increase version number to 1.2.1 for our next actual release.

Dev mode enabled some debugging flags such as:

* Simpler proof of work
* Whisper enabled by default
