* added tests for java type argument recording
* implemented recording type arguments for java ExpressionMethodReferences
* changed type_argument edge to originate in generic type
* added type_usage edge for type_arguments that originates in context (e.g. calling method)
* add compiled statement for batch inserting 100 occurrences at once
* removed unnecessary primary key from component_access to get rid of additional index table
* changed explicit check for existing symbols when injecting to implicit check in insert statement (insert or ignore)
* improved performance of adding edges by replacing edge multi part index with in-memory-index
* added in-memory-index for node table
* added in-memory-index for local_symbol table
* added in-memory-index for lource_location table
* moved setting storage mode to SqliteIndexStorage, because storage modes are not used anywhere else.
* don't store current mode as member because re-creating an existing index takes no time.
* add getter for name of SqliteDatabaseIndex
* removed unused method from persistent storage
* fixed crash when storage access proxy tries to access a deleted storage pointer
* refactored StorageAccessProxy implementation to use macros to generate proxy methods
* improved performance of "prepare indexing" step for all cxx source groups except empty
* unified code for filtering to contained file paths of source groups
* cleaned up code of SourceGroupFactoryModules
* fixed building longest common prefix array for full-text search by making values not relative the the charcode of the "a" character, because this would result in characters (e.g. "_") having a negarive value.
* centralized all file path caching in CanonicalFilePathCache
* added cache by clang::FileID
* moved FileRegister into CanonicalFilePathCache and removed it from AST* classes
* only record files once
* all dialogs for the indexing usecase can be hidden regardless of project state
* fixed some dialogs could not be shown
* pass dialogview into project and all indexing tasks
* pass application to project and tasks
* pass log directory absolute to indexers
* pass app and user paths absolute to indexers
* removed QCoreApplication instance from indexer process
* removed mutex from ConsoleLogger
* updated shortcut window
* renamed code reference menu items
* Show graph legend via 'legend' command or '?' button in the lower right corner
* Legend is not interactive: nodes and edges not clickable or moveable
* CXX and Java node types are mixed
* added clang system headers to data folder of Sourcetrail repo
* added clang system header search directory to detected directories on windows
* updated migration to add clang system header search directory on windows
* updated windows installer and portable package to include compiler headers
* updated linux package
* cleaned code of path detectors
* unrelated removal of unnecessary code in LicenseChecker and UpdateChecker
* switched SearchIndex and HierarchyCache to std::unique_ptr
* use move semantics and in-place initialization in StorageTypes and SearchIndex
* improved autocompletion speed by fixing contained node type checking
* added new location type
* refactored old recording code
* record signature locations for cxx functions and java methods
* added signature locations to sample project indexer tests
* ignore signature locations in ui
* signatures in tooltip with qualified name of the function/method
* added test for finding signature location of constructor with initializer list
