Improvements list

Here is the list of minor improvements, will be added whenever the new idea comes out.

1. Search values: RU always search strings.
1) A new command like "sv" will be added to search values.
2) Add a search dialog with hotkeys?
3) hex: "sv 0ffh", dec: "sv 255"?

This is done @v4.91

RU v4.90

Again this is just a minor improvement requested by the user:

Improved search string performance by using Boyer–Moore–Horspool algorithm. It is around 5 times faster.

Please note that I did not fully test this, not sure if it works properly.

RU v4.89

This is still a minor bug fix version. The hanging problem is still not solved yet. (Fixed @v4.92)

1. Display PCIe base address in command line while detecting
Please report the address when it hangs.

2. Fixed F6: list PCI will have last page empty sometimes.
