* Filter by regex in string view
* Dont recompile the regex for every string, display error message
* localization
* Use data->Buf for pattern creation / searching
The filter string seems to get updated after the callback finished.
Therefore the search string was always 1 character behind the actual
string in the textfield when calling find() / creating the regex.
* Build refactoring and initial plugin support
* Possibly fixed linux / mac build
* Added libdl to libglad build script
* Add glfw to imgui dependencies
* Refactored common functionality into "libimhex" for plugins
* Added plugin loading and example plugin
* Added proper API for creating a custom view and a custom tools entry with plugins
