This can recursively find files in a directory that's not in physfs search
path, this is needed for mapeditor needs, esp the file browser.
We do not want to limit users to the application run directory
so we have to use this.
This function uses boost filesystem.
Prototype:
g_resources.getDirectoryFiles(directory STRING, filenameOnly BOOL,
recursive BOOL)
filenameOnly is there if we want to just get the filenames in the
directory.
recursive if we want to loop directories in the directory.
lua_newtable() definition:
#define lua_newtable(L) lua_createtable(L, 0, 0)
This simply allocates space for 0 fields, meaning, if we push any
values into this array, it will re-allocate the array, which is bad.
This function statically allocates an array, so it's ready to have
X fields into it.
Performance tests:
lua_newtable

lua_createtable

These tests were done on an AMD 8350fx CPU, single thread used.
narr: This is for fields that just have an index, e.g. arr[0] etc.
nrec: For fields which needs like arr.a, arr.b etc.
This is how many times each of the functions can run per second, as
you can see about 1.7x the calls to lua_newtable.
All credits goes to @dalkon, he was too lazy to do it by himself, and
asked me to do it for him.
