Extracting SFRs when launching winIDEA

When launching winIDEA IDE Special Function Registers (SFRs) are expanded to a dedicated SFR location on your computer.  If winIDEA detects that the SFR database is corrupt, missing or does not match to winIDEA version, it restores it.

Note that SFR database could get corrupt if:

• You are using a tool (e.g. CCleaner, PrivaZer ...) which cleans that folder on Windows start or
• You were running a different winIDEA version before
