Fix/static ip display

[KomelT]

I added convertIntToIpAddress() and convertIpAddressToInt() .

It is a little janky but it converts INT to IP:

And also IP to INT:

The problem is that validator inheritances types from protobuf, so it expects a number instead of a string:

Can they be decoupled?

export class NetworkValidationIpV4Config {
.
.
.

@KomelT I'll take a look at this when I'm finished with #266

@KomelT is this ready for prime time, it seems to be working for me
