Hdl-checker

* Changed a couple of aspects of the server suggesting to use a config file
* Only issue the notification if the user hasn't specified a config file already (fixes 77)
* Also increased the time to trigger this from 15 to 30 seconds
* Invalidating cache file on version change (fixes 74)
* Disable logging and stderr when starting the server via `--log-stream NONE` and/or `--sterr NONE` respectively (fixes 73)
* Adding hook to `__main__.py` to allow python -m usage
* Added some support for `textDocument/references` LSP method
* Please not that this only provides references for items that HDL Checker knows about to support inferring libraries and determining the compilation sequence

* Fixed an issue with the legacy prj file parser (69)
* Fixed an issue when handling the rebuild project HTTP command (70)
* Handling git not being installed properly (fixes 72)
* Fixed potential decoding issue when reading a file with non utf8 characters
* Changed default GHDL flags when compiling a target file to `--warn-runtime-error`, `--warn-reserved`, `--warn-unused` when compiling a target file (scope = single)
* Optimized git ignore check to only check files that are not on the repo (should improve performance on Windows)
* Fixed an issue where a Verilog file might not be compiled as a dependency if a VHDL file used an entity defined in it
* Handling Verilog libraries the same way as in VHDL to allow Verilog units to be instantiated from VHDL correctly

* Verilog/SystemVerilog
* Fixed issues with parsing and identifying dependencies on Verilog and SystemVerilog
* Verilog/SystemVerilog headers will be parsed as regular sources; the dependency resolution algorithm will compile needed files and pass the include paths to the compiler
* Auto source discovery now also adds .svh and .vh
* Fixes
* Fixed an issue where dependency resolution failed if both package declaration and package body were on the same file
* Fixed an issue where diagnostics from the saved file were being mixed with diagnostics generated by new edits
* Fixed an issue where the default VHDL library wasn't always being used
* New version notification won't trigger when installing from git via `pip install git+https...`
* Fixed an issue that prevented identification of files that need to be recompiled when when using XVHDL
* Improvements
* Dependencies that could not be resolved to paths are now reported (61)

* Removing dependency on 'sort' parm for git ls-remote (should have gone into v0.6.5!)

* Fixed 49 (can't get messages when source has non standard characters)
* JSON config `includes` key now supports folders (will search for RTL files). The [wiki][wiki] has been updated as well. (53)
* JSON config file now handles glob patterns on file names. The [wiki][wiki] has been updated as well. (54)
* When not using a config file, file search will honor ignored git files (55)
* Errors from dependencies are now published (they were previously being silently ignored). This helps a bit with 58.
* Fixed an issue with parsing XVHDL output
* Fixed an issue that prevented recovering state from cache, resulting in rebuilding the entire project when restarting the server

* Fixed an issue that would prevent the LSP from starting if there's no workspace open
* Ignoring references to library "work" when determining the most common library used for a given design unit
* Server will now report when a file's library can't be uniquely determined
* Adjusted minimum severity to info (VS Code doesn't seem to show hints)
* Fixed an issue where some messages were being displayed with the wrong line number
* Server will now restore its working directory if it gets deleted
* Server will now report if a new release of HDL Checker is out
