LIBSQLITE3_FLAGS for bundled -> SQLITE_FLAGS

This flag was added in a9b700c but never documented. Here we change the
name to more closely follow SQLITE_MAX_VARIABLE_NUMBER etc; and
document its existence in README.md.

``` ```
* When using the `bundled` feature, the build script will honor `SQLITE_MAX_VARIABLE_NUMBER` and `SQLITE_MAX_EXPR_DEPTH` variables. * When using the `bundled` feature, the build script will honor `SQLITE_MAX_VARIABLE_NUMBER` and `SQLITE_MAX_EXPR_DEPTH` variables. It will also honor a `SQLITE_FLAGS` variable, which can have a format like `"-USQLITE_ALPHA -DSQLITE_BETA SQLITE_GAMMA ..."`. That would disable the `SQLITE_ALPHA` flag, and set the `SQLITE_BETA` and `SQLITE_GAMMA` flags. (The initial `-D` can be omitted, as on the last one.)
* When linking against a SQLite library already on the system (so *not* using the `bundled` feature), you can set the `SQLITE3_LIB_DIR` environment variable to point to a directory containing the library. You can also set the `SQLITE3_INCLUDE_DIR` variable to point to the directory containing `sqlite3.h`. * When linking against a SQLite library already on the system (so *not* using the `bundled` feature), you can set the `SQLITE3_LIB_DIR` environment variable to point to a directory containing the library. You can also set the `SQLITE3_INCLUDE_DIR` variable to point to the directory containing `sqlite3.h`.
