* fbt: added hooks for build & dist environments
* Moved env hooks to an optional file
* Fixed var name
* Added fw origin to device info
* Bumped device info version

+
+To introduce changes to firmware build environment that are specific to your fork:
+
+    create a file "scripts/fbt/fbt_hooks.py"
+
+With it, you can define functions that will be called at specific points of
+firmware build configuration, with environment as an argument.
+
+For example, you can define a function `PreConfigureFwEnvionment(env)` that
+defines that will be a part of SDK build, so applications can
+use them for conditional compilation.
+
+Here is a list of all available hooks:
+
+    PreConfigureFwEnvionment(env):
+        This function is called on firmware environment (incl. updater)
+        before any major configuration is done.
+
+    PostConfigureFwEnvionment(env):
+        This function is called on firmware environment (incl. updater)
+        after all configuration is done.
+
+    PreConfigureUfbtEnvionment(env):
+        This function is called on ufbt environment at the beginning of
+        its configuration, before dist environment is created.
+
+    PostConfigureUfbtEnvionment(env):
+        This function is called on ufbt dist_env environment after all
+        configuration and target creation is done.
