Fix windows paths in development

[frandiox]

Closes #476
Closes #499
Closes #529
Includes #528

This one was reported in this comment.

the new URL(file:///${relativeFilePath}) is not accepted on Windows, removing a slash at file:/// so it becomes file:// fixes the problem on Windows

[frandiox]

I've tested this branch on Windows and it seems to work, including:

• init
• dev + virtual routes
• generate route home
• build
• preview
• check routes

Should I run anything before I run the command @frandiox?

@Andi365 we need to cut a new release before the changes are published
