GXemul Code2

GTKMM GUI test: Connecting to the "activate" signal of a text
entry, so that commands are executed once ENTER is pressed;
this does not work with tab-completion and command line
editing though, since only ENTER is signaled.

Implementing support in the CommandInterpreter for running
methods on components. If a component name is "executed" with
no method name given, the component tree is dumped. (This means
that there is no need for the 'tree' command anymore, so it
has been removed.)

Implementing the first component method: "unassemble" for the
CPUComponent.

Translating some more strings into Swedish.

Beginning on internal support for instruction disassembly (not user-accessible yet).
Importing some MIPS defines from GXemul 0.4.6.3.

Spelling fix: emulte -> emulate.

Importing opcodes_mips.h from GXemul 0.4.6.3.

Links are now generated from component names in machines.html
to corresponding component_xxx.html pages.

The ListComponents command now shows the short description of each command.

Introducing "visible class names" in addition to the normal
class name, for components. This makes mips_cpu0 show up as
just cpu0, which is much nicer.
uint16_t, 32_t, and 64_t state variables are now outputted in
hexadecimal form in ToString(), for readability.

Adding a comment about "component paths" to the source code documentain main page.
