In this commit we add support for loading multiple components into one ghcide session. The current behaviour is that each component is loaded lazily into the session. When a file from an unrecognised component is loaded, the cradle is consulted again to get a new set of options for the new component. This will cause all the currently loaded files to be reloaded into a new HscEnv which is shared by all the currently known components. The result of this is that functions such as go-to definition work between components if they have been loaded into the same session but you have to open at least one file from each component before it will work. Only minimal changes are needed to the internals to ghcide to make the file searching logic look in include directories for all currently loaded components. The main changes are in exe/Main.hs which has been heavily rewritten to avoid shake indirections. A global map is created which maps a filepath to the HscEnv which should be used to compile it. When a new component is created this map is completely refreshed so each path maps to a new Which paths belong to a componenent is determined by the targets listed by the cradle. Therefore it is important that each cradle also lists all the targets for the cradle. There are some other choices here as well which are less accurate such as mapping via include directories which is the aproach that I implemented in haskell-ide-engine. The commit has been tested so far with cabal and hadrian. Also deleted the .ghci file which was causing errors during testing and seemed broken anyway.
