Resolve "FEATURE: Use time stamp from kurisu in update process"

Closes #109 (closed)

• New way of updating the db by re-using fileds when possible
• Check with the repo_timestamp in the repo module instead of getting the file's mtime
• Default the repo_timestamp to the file's mtime at upgrade time

 - Add: restore the "install" operations. When typing `make install` or `ninja install` the binaries, scripts and manpages of lektor will be installed into the `CMAKE_INSTALL_PREFIX`
 - Add: the folder permission is not settable at the creation of it, the value is modifiable in the config file at `database/dir_permission`
 - Add: the regex used to populate the database from disk is now modifiable from the config file, the keys are `database/{types,categories,languages}`. Those fields must only contain alpha characters and commas
+- Add: re-use more informations from databases when upgrading the database because minimal version where added to the different fields in the table descriptions
 - Fix: fix incorrect parsing of lists of commands with multiple arguments: the parser could overrun the correct command buffer and insert a '\0' between the next command and its furst argument
 - Fix: fix issue #100 -> the `database_queue_add_id` won't add ids that doesn't exist
 - Fix: be explicit about truncated commands, when a command is truncated, all the bytes after the end of the new string and before the end of the old string are not set to '\0' for safety

 - Fix: if a kara is not available it will be downloaded even if there is a file on the system (may be filtered out by a user specified URI)
 - Fix: rely on CMake to find OpenMP support for a correct error reporting. OpenMP support is also marked in the README now
 - Fix: no more SEGV when we don't find the module specified in the config file

 - Fix: properly set LC_NUMERIC to C to avoid SEGV in mpv with module sdl2

 - Change: not finding the module specified in a config file is now a fatal error, the error message has been improved
 - Change: no longer set the locale, we only check if the local is an UTF-8 one and abort if it's not
 - Change: all the functions in the command trie have the same signature (less bloat here)
