Debugger: Support setting substitute path by regexp

This is useful when there are multiple build machines with different
path, and the user would like to match anything up to some known
directory to his local project (variable support will also be useful -
will try to add that later).

Syntax: (/home/.*)/KnownSubdir -> /home/my/project

Capture group will be replaced by the value.

In this example the substitute path will be (in case a source string
found such as /home/SomeUser/SomeProject/KnownSubdir/foo.cpp):
/home/SomeUser/SomeProject -> /home/my/project
