Standardization of the names of files and resources in which the name of the program is used.

[beliys]

Different versions of the name of the program are now used in different places. In some cases, meow-sql is used, and in other cases, meowsql.
For example, in the name of the repository, binary file compiled from qmake and for the .pro file, we use meow-sql, and for the rest, meowsql.
This does not affect the operation of the program in any way and is not particularly critical, but for maintainers who will create packages it would be more convenient to use a variable like ${pkgname} for all cases when the name of the program is used.
Also, an internal perfectionist would be happy with such changes.
