New features

[js] Add a compute method for off-exec-thread computations ; add a layoutTextLines operation which allows to break a text so that it fits a rect (roughly!)
[search] WIP on searching addresses within processes and ports in the search text box
[expressions] Add a 'contains' operator to check whether an array contains a value, or a string contains a substring

Bugfixes

[avnd] Fix midi scroller bugs
[scenario] Fix some drag and drop cases (dropping .layer files was broken)
[gfx] Add missing headers for make install (should fix some issues with building templates / addons / jit stuff)
[lv2] Fix memory leak in C API (yay) for ui detection

[search] Optimize searching for addresses in state

[ui] Fix that the ports would sometimes not show up at the right place
[camera] Set mode to stretch until we add a way to configure it
