Properly fail if no appropriate Disassembler can be constructed
Currently, for mipsel there is no InstructionAnalysis available for some

Add testcases for disassembler
Testing basic functionality of the LLVM-based disassembler on amd64/elf

Preliminary LLVM-3.6 support
Allows llvm-3.6 in cmake and does compile with 3.6. However it
does *not* work! It will segfault right away. One of the suspects is
different base for addresses used in llvm's getInstruction() and family.

Install the guile-frida-bindings into system library path

Restructure InformationManager
- Signals now all use Event objects to communicate information and all
share a common sane interface
- Organize signals consistently and grup by signal name
- Dynamic and local functions are now handled almost the same
- Changes all over the place to fix users for these changes
- proper iterator access for the maps so one can actually iterate over
all functions (for example a script)
- ignore these iterators where they would be most usefuill (scripting)

Add log widget to lower dock
Make the lower dock container agnostic the former ScriptingDock now is

Make InformationManager responsible for cleaning Blocks / Functions

Move Function/BasicBlock to core and clean up includes
Function and BasicBlock are considered part od the Data Model and part
of the core. Move them there.
Also remove lots of #include from the headers and replace them by
forward declarations. This should make compilation units smaller and
remove the huge number of users for each header -- speeding up
compilation and making users explicitely include stuff they use.
