In some cases, one wants to use system TClap (for instance, when one has
patched tclap installed)

Although #pragma once is not a standard, compilers nowadays usually
support it. We don't have any tricky build system so we should be OK.

This also fixes many errors regarding using reserved identifiers (names
starting with double underscore).

Fixes a bug where wrong CMake variable was checked. Instead of checking
for existence of variable VERSION_STRING the code checked for existence
of variable "value_of(VERSION_STRING)".

Added support for testing aql files (tests/aql).
Removed alib2integrationtests/ in favour of tests/ directory.

Sorry for a messy commit.
Closes #198.

We used 'contrib' name improperly [1,2].

Simplify versioning by CMake. Uses git version in the format
"<major>.<minor>.<patch>.r<commits-since-version-tag>.g<hash>(-dirty)?".

Adapts Doxygen generators to changes in previous commit.

Remove CMakeLists.txt generator scripts from build phase. Replaced with
CMake's GLOB that can re-run every time the build is invoked. We can
also drop the Python dependency now.

Removed header installs which will be redesigned in future commits.
