Make the Solidity repository standalone.

This commit is the culmination of several months of work to decouple Solidity from the webthree-umbrella so that it can be developed in parallel with cpp-ethereum (the Ethereum C++ runtime) and so that even for the Solidity unit-tests there is no hard-dependency onto the C++ runtime.

The Tests-over-IPC refactoring was a major step in the same process which was already committed.

This commit contains the following changes:

- A subset of the CMake functionality in webthree-helpers was extracted and tailored for Solidity into ./cmake.   Further cleanup is certainly possible.
- A subset of the libdevcore functionality in libweb3core was extracted and tailored for Solidity into ./libdevcore.   Further cleanup is certainly possible
- The gas price constants in EVMSchedule were orphaned into libevmasm.
- Some other refactorings and cleanups were made to sever unnecessary EVM dependencies in the Solidity unit-tests.
- TravisCI and Appveyor support was added, covering builds and running of the unit-tests (Linux and macOS only for now)
- A bug-fix was made to get the Tests-over-IPC running on macOS.
- There are still reliability issues in the unit-tests, which need immediate attention.    The Travis build has been flipped to run the unit-tests 5 times, to try to flush these out.
- The Emscripten automation which was previously in webthree-umbrella was merged into the TravisCI automation here.
- The development ZIP deployment step has been commented out, but we will want to read that ONLY for release branch.

Further iteration on these changes will definitely be needed, but I feel these have got to sufficient maturity than holding them back further isn't winning us anything.    It is go time :-)

+# Bash script for installing pre-requisite packages for solidity on a
+# variety of Linux and other UNIX-derived platforms.
+#
+# This is an "infrastucture-as-code" alternative to the manual build
+# instructions pages which we previously maintained at:
+# http://solidity.readthedocs.io/en/latest/installing-solidity.html
+#
+# The aim of this script is to simplify things down to the following basic
+# flow for all supported operating systems:
+#
+# - git clone --recursive
+# - ./install_deps.sh
+# - cmake && make
+#
+# At the time of writing we are assuming that 'lsb_release' is present for all
+# Linux distros, which is not a valid assumption.  We will need a variety of
+# approaches to actually get this working across all the distros which people
+# are using.
+#
+# See http://unix.stackexchange.com/questions/92199/how-can-i-reliably-get-the-operating-systems-name
+# for some more background on this common problem.
+#
+# TODO - There is no support here yet for cross-builds in any form, only
+# native builds.  Expanding the functionality here to cover the mobile,
+# wearable and SBC platforms covered by doublethink and EthEmbedded would
+# also bring in support for Android, iOS, watchOS, tvOS, Tizen, Sailfish,
+# Maemo, MeeGo and Yocto.
