[Enhancement] Add support to "F5"（Pseudocode window）

[RandLily]

As a noob，I like using "F5" to debug , but I find this plugin is not synchronize with original ida stack and registers in "F5" ( Pseudocode window ) when step_into or step_over 。So I read the “dbg.py” and "IDADoc"，try to find a "srcdbg_step_over" and "srcdbg_step_into" hook to "reload_info"，but I failed。I really appreciate it if you can add this synchronous ability。
