Decrease initial size of symbol cache hash table

Browse Source 
Using 2^23 allocates 128MB memory for the hash table. Seems like
a waste of memory, especially for small scripts.

For example, I didn't notice a huge difference in time between 1000
and the old number when compiling most of YSI includes and tests.
Hash tables double in size when they need more space, it's pretty
efficient (at least this implementation does so).
