* Soft cap is 1000 to avoid going above the set heap size.
Also fixes:
* Adds entity flags to checkpoint data.
* Only sets your movetype to the one in the checkpoint data if it's either the walk or ladder types, so you can save while noclipping but teleport normally.
`shavit_misc_prespeedlimit`'s behavior was changed and is now `shavit_misc_prestrafelimit`. The value determines the maximum allowed prestrafe in the start zone *added* to the style's run speed. So i.e., Scroll can prestrafe up to 280 (in reality, 278) and Normal can up to 290.
The default settings for `shavit_core_blockprejump` and `shavit_misc_prespeed` were changed due to this commit.
`shavit_misc_createspawnpoints`'s default setting was changed to 6 as 32 didn't make much sense.
